Replace the tyres?

gopz · 19th September 2007, 10:08

Hi TBHP! I have stock tyres on my 2001 M800 which has done about 51000KM till date. The tyres are good and might go on for another 10k KM (well maintained car isnt it

)

...but the manufacturing date on the tyre is Dec2000

Should I keep these tyres or just throw them away and get new ones? Because they are almost 7 years old!

I had plans to sell this car, but now I ve decided to keep it.

I am planning to go in for 145/80 R12 when I change them next.

Shelf lfe of rubber is around 5-6 years, its good if you can change your tyres now.
Why you want to switch to 145/80 R12??

since youve decided to keep the car then why not get new tyres? anyway your tyres are pretty old. also are you going to get alloys? then upsize to 13".

I am influenced by ram's thread..it improves the handling and ride.

@ahskay1234: I am not going for alloys

Akshay1234 · 19th September 2007, 11:14

you could get wider steel rims and get 165/60 r12 potenza g3s.

now that would improve your handling.

It will surely improve the ride but don't think there will be any improvement in handling.

In the market GIIIs are totally out of stock AFAIK.

gopz · 19th September 2007, 11:30

165/60R12

well that would bring down my mileage and pick up, isnt it?
I'd rather stick to 145/80R12

i doubt 12" would be.

gopz - that would bring down your mileage a bit but if your doing mods on your car then it would be fine. i remember a thread you had created about mods for your car.

Yes, its better to stick with 145/80-12 for an old car.

Chances are almost nil otherwise it would be an old stock .

yup..im going for a K & N + free flow later

how much mileage would go down with those tyres? I am OK with a drop in 2km but if its going to drain my petrol tank then I will stay away

and how much do these tyres cost?

gopz, better decide whether you want performance (handling) or comfort.
145/80R12 is good for comfort (and economy) while 165/60R12 would give you better handling (but reduced ground clearance).

I want high GC and comfort/economy.

I called up a dealer here, he said that potenza g3 is out of stock (12")

I probably will stick to 145/80R12 - which is the best tyre in this size?

How are Bridgestone Turanza's ER-60 145/80R12??

mobike008 · 19th September 2007, 13:29

Turanza's are great tyres for a nice comfortable ride with a bit of performance thrown in. Potenza's are out and out performers.

165/60R12 will give you a wheel with outer diameter of 502.8 mm (19.8") with 9.9 cm of rubber sidewall.

145/80R12 will give you a wheel with outer diameter of 536.8 mm (21.1") with 11.6 cm of rubber sidewall.

Ergo, 145/80R12 would give superior ride quality and 17 mm more ground clearance than the 165/60R12.

As the 165 mm wide 502.8 tall tire will have both more grip and lower diameter, it will yield poorer fuel economy than the 145 mm wide 536.8 tall tire.
