on my old car i had 225 section s03's on the back when i bought the car. It was somewhat 'drifty' at the rear under cornering.

I changed the rears to the proper s02's and the handling improved drastically.

If you see the rear s02's alongside another tyre you'll see how small the rain channels are in the s2000 specific s02 and why you need a wider tyre if you're not going for s02's.

with reference to the torque steer you describe, does the car pull in one direction under heavy throttle, and then pull the other way when you lift off?

this sounds like the classic tyre pressure problem. You'll probably find that one of the rear tyres is low on pressure.

The small rain channels are to maximise the amount of rubber contact rubber you have for a given size of tyre. Hence the SO2's in the dry get better as they wear as the channels all but disappear its part of the make up of the tyre.

The F1's look the best bet as the shoulder and contact area of the tyre is also large. Having used these and others on different cars Id say that you had other problems if you found S03 to be causing you issues.

The whole Potenza range are very sensitive to wear as we all know once you get to a certain wear limit they fall off very quickly but are excellent while in the zone.

Since Bridgestone suggested that 3mm is their recommendation limit on the Potenza range Its possible to knock their tyres on or past this point as 3mm still looks like a lot of tread as we are used to the 1.6mm limit.

No, the problem i had with the rear of my car was specific to the fact i had 225 section s03's on the rear. In normal driving they were fine, but when you started pushing it, eg accelerating around a roundabout, the rear would break away quite early with the s03's. When i changed to s02's the rear gained a load of grip.

I like the sound of the GSD3F1, they are an awesome tyre for all round use. My only slight concern is the stiffness of the sidewall.

If Lickermats figures are right then they have the same width as so2 so there is no problem with that aspect?? (unlike previous/other 225 width tyres)

and at 331 a set that is a good price.

Hard to call that one IMO , but I

Sounds a lot like the rear wheel steer effect. I thought it was like torque steer too, and couldn't understand why the back was getting unstable at relatively modest speeds in the dry. It wasn't.

It's like that yes, turns the car right as you let off.

The first thing I did though was check and set the tyre pressures to 34psi. It's still there, slight though but noticeable.


I'm a bit confused by the above now though. I want to get some new rear tyres so lets say i go for T1r's or eagle f1's

225/5016 or 245/45/16 ?

After looking at my rears today, then weren't nexxan lol but I've forgotten what they are again (think it began with an H)

Thing is even at 225 they look too wide for the rims anyway, can't imagine what 245's must look like on the std rims?

Rear wheel steer effect?

No confusion , as mentioned the original FAQ on what was a "replacement" tyre for the rears was based on the fact that the OE SO2's have a larger section width than your average 225 tyre so most of the off the shelf replacements would be smaller than the So2
