Why would it be a problem when the rear is loaded?? Any particular reason for this? The lower profile (60 as against 80) shouldn't really foul with the fenders. The front is where there might be a prob i would think.

Hey Rtech & CrazyD,

Well firstly the OD of the 155/80 =~124mm & 185/65=~120mm.

My guess at the reason for the 185s touching is under heavy load is because either >
i- they stick out wider, past the wheel well, so load pushes the edge of the wheelwell into the tires.
ii- they are wider, so they touch the slight curve inside the wheel well when the load pushes it down. (The cuve that would go in the Left-Right orientation if you are looking at the car from the back..if you know what i mean.)

Heres a pic of a zen (dippys zen), what size certis's does it have dippy? 165mm?
It might sevre as a visual aid to why this happens.


Also, the reason it happens when the rear is loaded is because the front (on a zen) never gets large amounts of additional direct load on it like the rear would...

That would be my guess!

ps - Rtech, good point...didnt think abt eagle F1s not being available in 165/65...

[crazydiablo4484]

hey dippys must be 165s. Dont seem to be very wide. must be 165/65. but still just a guess!

[Dippy]

My tyres are the Michelins 155/70 R13 75H. Tubeless. They arent really wide that they come out of the car but they look pretty good. If you guys want I'll try to get some shots of the tyres for you

Cheers

[Rehaan]

Thanx Dippy,

So guys, now just imagine the tire being 3cm wider than that (1.5cm more extending outwards & 1.5cm inwards) =185mm
Seems like it might wanna touch the wheelwells when fully loaded!

Shouldn't be a problem if its loaded as i don't think the Zen has that much of travel in the rear suspension, but maybe if you over-loaded it! hmmmm!

[crazydiablo4484]

Ya zen does have a soft suspension. unless you change the springs with three adults at the reat it will scrub the wheel wells when over a bump.

[Jaggu]

yup the rear mudguards of the Zen are a pain

[Dippy]

Hey

Like I promised here are the pictures of my Zen's tyre










Cheers

P.S. When I turn right my right front tyre does touch the inside of the mud guard sometimes

[GTO]

Dippy,

In the second picture, the tyre clearly looks like its been repaired i.e. the sidewall had torn (happens when run over a divider or driving on a flat) and that its been "patched" up by a local tyre guy. Its near the M-I of Michelin. If it hasnt happened by you, chances are that the previous owner is to blame.

I would have to see it in person to confirm, but if it is patched up thats a very very dangerous situation. That repair job could tear up completely under stressful conditions and you will experience sudden loss of control. I suggest changing it immediately.

hey pals...................can u explain me abt all those numbers (regarding the sizes) and those ratios like "155/R13" abt alloy wheels and the funda behind them????wat are magnum wheels ?

[Dippy]

Hey GTO

The tyre you have mentioned has been repaired . Infact someone outside my office had once done some mischief when my car was parked there. But all rest assured its a proper repair job done by professionals. It's been valcunized with proper machinery and not just patch work. Work has been done at Sumit's shop The tyre wasnt torn though. Sumit's been there in the tyre business for 75 years so I guess he knows better.

Thanks for the concern though pal.

Hey Aksh,

Here is a link to help you understand the tire sizes and ratings, check it out and then come back to us with any further questions..How Stuff Works - Tires

And about "Magnum alloys" i guess you mean "mag alloys" which is short for magnesium alloys. Magnesium being a type of metal that may be used in alloy wheels.
The thing is that magnesium has some advantages (lighter weight etc) when used in alloy wheels, but also some major disadvantages (like magnesium might catch fire). So, mag alloy wheels are usually kept for the race track and not for road use.
Most of the time people use the term "mag alloys" incorrectly to reffer to alloy wheels which are made of aluminum alloy (like most alloy wheels seen on the road today are)

Hope that helps

ps - thanks for the pics dippy, how many km on those tires?

[crazydiablo4484]

Mag alloys are available for road use also. They are damn expensive but so are found only in the high end cars.

[Dippy]

Hey Rehaan bought the car with 40k on the odo . Fitted the Michelins immediately after I took delivery of the car. So Almost three years down the line I have done about 37 k with these tyres.

Cheers

[crazydiablo4484]

wow 37k? Amazing you dont spin the wheels dude or are michelins that good. I dont think my tyres last more than 25k
