S02's on the rear...????

[smcquill]

Its come to that time when I need to replace the S03's on the rear of my Griff, been reading through the threads...however has anyone got any experience of putting S02's on the rear whilst you still have S03's on the front..?

Any advise welcome...

thanks

Can you still get S02's...?

[Johno]

S02's suitable for TVR's haven't been made for about 6-8yrs. There are some Porsche specific ones around but very different tyre ware stiffness. S03's haven't been made for 2-3yrs either . . .

How many miles do you drive !?

Toyo T1R's for an all round road tyre. R888 if you want a road legal track tyre. These are the leading preferences.

Goodyear Eagle F1's are an alternative as well.

[LordGrover]

There are other options too... a few seem to be liking kuhmos for tracking; click. If you have a search there are plenty of options: click.

Recently put these SO2s on the rears with SO3s on the front, car drives fine. What's good enough for Porsche is good enough for me.

[Johno]

Perhaps they're not Porsche specific, but my understanding is that they are. Porsche with the engine slung behind the rear axle, wouldn't naturally point at these tyres being suitable for a TVR, but if you're happy with em, crack on

Its not about being good enough for Porsche though is it...? Its about sidewall ridgidity.

[Johno]

^^^^^^^^

Exactly that . . .

Funny, could have sworn the Porsche 924, 944 and 928 were front engined.

I'm reasonably sure the SO2s I just put on have far more sidewall rigidity than the Toyos I took off.

[450Nick]

The S02s that were designed for TVR were SO2pp's (Pole Position) - long discontinued. IIRC these had less stiff sidewalls, more like the Toyo T1Rs which IMHO are the best road tyre for a TVR. Standard S02s are too stiff IIRC as they are designed for heavier cars (Porsche).

When I got my car it had S03pp's on (the owner thought they were similar to the S02pp). Unfortunately this was not the case and they had ridiculously stiff sidewalls and made the car a right handful on the limit. They were removed fairly sharpish and I then went to Toyos. I've since tried Goodyear Eagles and found them pretty similar in their characteristics to the Toyos. But having gone through a set now, I wouldn't put anything but Toyo R888's on. The difference is akin to putting a supercharger on the car.

Fascinating! So Bridgestone designed and manufactured a version of the SO2 specifically for TVR. Do you know if Bridgestone did this for the RE71 and SO1 as well?

[LordGrover]

Who'll be the first to give in/get fed up?

[davep]

My advice to the OP: don't put SO2s on the rear of your TVR, they're exclusively for Porsche 911s, apparently.

Me! I give up. I can't be arsed to argue any more!

Indeed they are front engined, no argument there . .. In fact one of them even had a V8 as well tucked in the front. . .. Do you think all the tyres were the same then? If it's a Porsche then they all get the same tyres? .. I seem to doubt that. . .

S02PP's were factory fit from TVR and are no longer available. I understand N3's were factory fit for 911's and are still available. Probably due to the size of the market and German laws on having to provide spares for 9,000,000 years after production has ceased (no bad thing).

The point on sidewall rigidity is that Toyo's for example are softer and that is the recommended style of tyre to have with a TVR. This could all of course be nonsense and lot's of debate, conjecture and several thousands of miles completed on differing tyres by differing people coming to the wrong conclusions. It could also be argued that many of us wouldn't be able to tell the difference and wouldn't know what we were looking for in the first place. However, the common consensus has evolved that softer side walls are more suited to our applicatin and N3's are a stiffer sidewall, more suited to a beetle . . . er Porsche, of the 911 variety.

As I said earlier, if they're good for you then crack on . . . sorry to have upset your day by having differing knowledge, opinion and being prepared to state it, I always thought that was what the forum was for . .

^ That was much better than my reply

To my mind the most amazing thing is that this guy appears to have owned TVrs for 10 years and then posts this:

Whoa there tiger! There's no need to resort to abusive language like that. That was a bit of a 'goading' question I admit, and apologies for that.
