No, I'm on the stock size and on the stock Goodyear Tyres and I'm experiencing it from the 30th kilometre.

Will upload a VCDS Scan, with the Steering Angle Sensor value at the centre position. If it isn't, I'll try adapting it to the correct centre position and share if it helped.

1. Check the front wheels for free rotation. Jack up the front end - rotate both wheels with your hand and check the speed and time. Both wheels should be similar. If not, adjust the wheel bearings or check brake bite
2. Check ride height. Should be same left to right.
3. Check Camber angle. Usually the vehicle will veer to the direction which has more positive camber
The above points may or may not work in your case. I just

Will try this out. I've already tried the free play when the car was on the service centre lift and the bearings seemed fine. Will do the other checks.

Yes, you're right. This is also common when the engine mounts are bad, especially the gearbox or engine side mount. But the pulling due to a bad mount is particularly felt when you accelerate. On this Polo TSI, the pulling seems to pause when the car is being pushed hard, making me feel the mounts are just fine. I have a strong feeling the fault lies in the engine vibration pattern. If it is a design defect, I'm gonna regret buying this vehicle, since I spent a majority of my time in it crawling around the city, and the hand does hurt tugging the wheel to keep the car straight.

Hi Sen,

I did bought 2019 Skoda Rapid and upgraded my tires to continental 195/60/r15 from 185/60/R15 (Goodyears) after roughly 2000 kms. I felt the exact issues which you are describing after the change. I did go to 2-3 tyre alignment shops and to ASC as well and wasted a lot of money.

Guess what? I gave up trying to correct the issue and waited to see the effect on the tires. To my surprise, after 1500-2000 kms the tires behaved normally and the left veering issue completely vanished on its own.

I guess the best answer that comes to my mind is some settling time with continental tyres. I never faced this with other brands and now with your post and a friends' same experience kind of supports my hypothesis.

I got the EXACT same feeling while driving as mentioned by @fluidicjoy.

I would suggest you to give it some time, let is run for a couple of thousand kms and then check.

Best wishes.

A simple tyre rotation in sequential manner and test drive after each change should solve the problem.

Had this problem on a brand new set of Michelin XM2. The problem was solved with the above approach.

Will the reference toe values have to be re-adjusted when an up size is done?

Just to add, my vento highline+ comes stock shod with 195/55/R16 tires. The same sized tires were replaced with Conti UC6s.

Thanks for this! Let's hope for that. I have about a 1000 kms or so left to go and did notice that the veering reduced (I thought it was that third alignment) after the 1000 km mark (ODO at 1300ish now)

What you say might as well be true and applicable to continental tires, but fluidicjoy above is on stock Goodyear tyres, so the doubt remains

Wow! Thats the third user who shifted from Goodyear to Continental and has faced the same issue!

[venkyhere]

usually pulling issues are due to caster imbalance between left and right. If the issue is minor, accelerating (torque applied to wheels by driveshaft) will drown out this imbalance and steering will feel perfectly straight. Easiest way to notice is to leave the steering on level road, and get off the A pedal. If the car pulls left or right => the torque applied by wheels on the driveshaft are different between left and right => clear case of uneven tyre wear (not applicable if new tyres) or caster asymmetry. What causes caster asymmetry ? either the way the suspension/steering assembly is mounted to the subframe or a manufacturing defect in the knuckle itlsef, in terms of symmetry between left and right.
Wheel alignment centers only touch the tie rods for adjusting toe. They can't do anything about caster difference, which has to be troubleshooted by an expert mechanic or by authorised service center (if those places have experts who do this).

I strongly suggest this aspect be explored before getting into another can of worms called engine mounts. (because if they are not worn and if someone removes them and fits them back imperfectly, you will have a new set of vibrations to deal with).

Hi Sen,

The tyres are tuned by manufacturers for a particular car to provide the best possible balance of ride and handling. They are quite complex and even if its the same brand and size the composition might be different. This used to be a major issue with HPS but with onset of EPS in modern cars it is possible for OEM's to tune it out through the steering calibration.

It might also to help to understand the amount of effort required to keep the vehicle on a straight line. Is it happening only in hands-off condition?

If the alignment values are confirmed to be within spec then these could be the following things which are wrong in the order of possibility-

- Swap back to OE tyres to check if the same left pull is occurring. If this resolves then the tyres sourced might not be a good fit/correct tuning of the car. There are many factors which are there like PRAT which help to ensure straight motion of a specific vehicle.

- After swapping to OE tyres if the same symptoms occur then you can raise a concern with VW service to check all the geometry hardpoints to see if there is any deviation in it. This may require major part changes and may not be rectifiable as well.

It would be not wise to take the car with aftermarket tyres to VW service as they may refuse to accept it as a warranty claim.

True especially the UC6. I recently upgraded my Honda's rear tyres to 195 UC6. Initial 1500 kms were horrible, I was cursing why did I even choose this. Now its really settled and rear comfort is way better than stock 175 Conti CC5

Give them some time, UC6 takes time to settle down. Might be the side walls are to blame here, initially it may be hard and then softens up as we munch on more miles

Issues ruled out:

-Tire pressures are equal between both front tires, so no uneven pressures at play here
-Three different tires rotated to the same front left position, same behavior continues
-Alignment checked at a tire shop, as well as at the service center, both claim zero issues

Steering rack/Suspension issue? What do I look at next to determine how to fix it?

Some brands have tyres with a square profile, while others have a bit rounded one. Suspension setups are calibrated at factory to the OEM supplier of tyres. Try to reducing air pressure on all (or just front 2 tyres) by 1-2 psi and see if it makes any difference. Other things like suspension mounts, wheel bearings etc should also be cheked.

Although I never faced exact same issue, in my Swift, I kept JK tyres at 30 psi, while Bridgestones at 29

I have endured the infamous “left pulling” in Punto for over 1 lakh km now. It can take away the fun from those long highway drives.

As usual , the Fiat service centre, at the time, gave vague reasons and not so confidence inspiring inputs ( chassis correction, steering column replacement etc). They had asked me to leave the car for a week. I realised they are trying to fleece me, never am I going to leave the vehicle with them.

After reading everywhere on the forum and the internet I realised it’s a very common problem with Punto and that too in BLR because of the fact that it has Hydraulic steering and the pull is amplified due to slightly inclined roads in BLR.

Then I came across pride cars in Bangalore and the lead technician Harish had some good reviews on the web. He solved the left pull in my car. It did take several test drives , tyre rotations and balancing. Now it drives like how it used to from the factory. As per his observation, the tyre Apollo Alnac is not suitable for Punto. A softer compound is recommended. However, do note that there will slight pull in the direction of road tilt, but that should not be concern.

So may be try to get hold of a good technician who is patient enough to go for multiple drives and isolate the issue.

Hope the issue gets sorted for you.

Hi Sen,
Though a lot of people have already weighed in on why your car veers to one side; I think it is a simple issue of improperly balanced wheels. Since you are already at Bengaluru, go to Madhus and ask them to rebalance your wheels on the Hunter Road Force Elite wheel balancer. All tyres have some imperfection or the other, which can lead to tyre pull. This balancer can correct tyre pull by perfectly aligning the tyre and rim according to their low/high points and suggest which tyres to pair together in the front and the back of the car, for the best possible results. Try it out and of course, do let us know if this helped. All the best!

[Sen]

Small update on this issue:

It seems the tires are settling in as some of the esteemed bhpians here have pointed out. The veering is gradually reducing to the tune where it's not as noticeable anymore, about 1350 kilometres in.

I'll chalk it up to the tire profile or wear erasing factory imperfections in the tires, but I'll keep observing the situation as it develops.

The three tires being rotated to the same spot on the front left were exhibiting the behavior probably because they were manufactured in the same batch (these tires are quite fresh!)

Quite a perplexing issue, but glad it's subsiding gradually. I'm happy to see we've created a resource for a variety of reasons that a car doesn't sit smack-dab center on a road however!

Thank you all for your insights and time, again.

.

Agree with the above points. Had faced the same left veering issue and spend a bit on diagnosis on my 2012 Skoda Rapid for 6 years until it was sold. I thought it was a one-off issue but it kept recurring after successive tyre replacement as well.

However, it caused no damage as such, hence made peace with it.

May not be true for all vehicles. Recently I shifted from Apollo to UC6's on my Ciaz, however I did not face any veering issue.

Glad that issue is waning out. Yes, the UC6's do take time to settle down. Mine are manufactured in week 44 / 2020

If you have had your wheels aligned recently, there are a few more things to check:-

1. The air pressure in your tires is inconsistent- Sometimes the solution is as simple as adding some air. Tire pressure fluctuates as you drive, and sometimes one tire will have less pressure than the others. If you find your car pulling to one side, the first thing you should do is check your tire pressure and add more if necessary.

2. You are experiencing tire conicity- Tire conicity refers to a problem in a tire when it’s made. Sometimes during manufacturing, one of the components becomes misaligned and causes the tire tread rubber to harden in a slight cone shape, rather than the proper cylinder shape. That causes your car to pull to whatever side the defective tire is on. This kind of conicity is apparent right away in new tires, and is covered under warranties.

3. There’s a worn out part in the steering or suspension- If it’s not your tires, it may be your steering or suspension causing your car to pull to one side. Worn out components will impact how your car drives.

4. Your brakes are wearing unevenly- An example of a brake caused pulling problem is stuck callipers, usually making grinding noises. Callipers are what apply the pressure to your brake pads, and if one is stuck part way back, your brakes will wear unevenly.
