Tyre wear

[Red_Bean_Bun]

Which of the following from your experience (not from published tread wear rating) has got the longest tread life -

- CSC3
- PS2
- F1 Assym

And is it normal for our tyres to go from a screeching sound to a stop versus a grinding sound to a stop as it wears (compound hardened ?) ?

Thanks.

Re: Tyre wear

PS2 definitely out of your choice if u looking for longer thread life. Never try CSC3 so no comment but i am happy with Asym so far.

Was contemplating CSC5P but I want to weigh it since I can't seem to google this out. But till then I guess its PS2.

Re: Tyre wear

I was on PS2 until I changed rims recently and got the F1 (since prices suggest it was value for money compared to PS2).

So far so good.

Re: Tyre wear

Kind of dumb but the skipping was caused by over inflation - Listened to some tyre shop Joes talk about the F1 Assym sidewall crack issues and overinflation was the way to go and pumped 36F / 38R into my tyres. Basically, they think its one set of pressure fits all.

Anyway I found that if you base the tyre pressure based on the total weigh of the car in lbs and divide over 100 - you should get a pretty good gauge of your "correct" tyre pressure -

(Vehicle Weight in lb/100) + 2 psi at heavier end + 2 psi all around if suspension and alignment are stock. If you are a big guy or if your vehicle is used to ferry people like a bus 90% of the time then include that additional laden weight as well.
Example: My Lau Pok Chia, 3,000 lb (actually 2998 lb but I rounded it off).
(3000/100) = 30 psi
Add 2 psi all around = 32 psi
Add 2 psi to heavy end = 34 psi at rear
With modified suspensions, the result is 30 psi front, 32 psi rear (if you have stiffened suspensions and like some comfort else ignore this - which I did).
So based on tyre Joe's advice of 36F / 38R - this would have been right for a zippy E92 but quite bulgy for tyres based on the weight of my car.
Deflated my tyres and all is well again even in the wet.

Re: Tyre wear

good stuff...

by the way, what is the life span (mileage) of the GoodYear F1s??? I know most of us here dont use any tyres over 1.5 years...
