I have got hold of a set of RL17's and the rears have brand new Bridgestone SO2's on them. The front ones need replacing shall I just get some SO2's for the front or are there better options?

I wouldnt touch bridgestones with a barge pole but thats due to personal bad experiences with them on 2 different cars.

I have Toyo T1R's on mine (all round) and they are fantastic.

Thats strange, I have heard nothing but good things about the SO2's. What were your experiences of them? Maybe I could put some T1R's on the front.

S02s are excellent (but check that they're not showing signs of aging as they are getting on a bit now). S03s were not well received, particularly as they replaced what was generally accepted to be a great tyre.

You'll struggle to find another pair of S02s now as they went out of production some years ago, stick a set of T1s on the front and it'll be fine.

The SO2's look like new with no signs of ageing. I will look to get some T1R's then.

They may not look aged but will probably have gone hard. not necessarily a bad thing as you will get much more wear from them, although less grip.

SO2's were stopped in 2003 so they will be at least 5-6 years old. As has been said they will have gone hard. I would not be inclined to use them for suopercar performance. T1R's would get my vote for raod tyres

Even ancient S0-2's are suspension breakingly fantastic. Put a few heat cycles through them (long burn-outs) and enjoy. At brands, our old S0'2s were touchably sticky in the way that some of the sprinters R888's get - by comparison, the T1R's (also good, it must be said) were'nt. We had S03's on the back briefly soon after - bloody dreadful.

Tyre goodness;

I have just been on the phone to Bridgestone UK tech dept. They said the tyres will be absolutely fine to use and that they will only start to be noticeably hard if there are any visible cracks. He also said there is a date stamp on them that can be found by having the 'bridgestone' at the 12 o'clock position and then looking at either 3 or 9 o'clock - there should be DOG written then four numbers. The first two numbers represent the week that they were made and the second two the year. E.g. 5208 would represent the last week in 2008.

They will be fine for at least 10 years apparently but it is illegal to sell tyres that are over 6 years old. I presume he means through a retailer and not second hand.

I also asked why they stopped making them and he said that he does not know and freeely admitted that they were a great tyre and the models that superceeded it are rubbish. Apparently tyre manufacturer is made at a Europe wide level and the individual company's don't get any say or even know why some tyres are discontinued.

That has linked to a list of loads of tyres. Was it meant to show SO2's?

It seems to imply that they have SO2's in the correct size for a cerbera front wheel (225/40 18).
You just need to select Bridgestone SO2 from the list of tyres on the right of the screen.

Shouldn't they be 225 35 18's on the front ? and 255 35 18s on the back.

In order to compensate for the narrower tyre and still preserve the rolling radius of the wheel, many go to 40 on the front and retain the 35 on the rears...

Beware when mixing brands front to rear on a Cerbera.

When SO-3s became unavailable I had to replace the rears on my car with T1-Rs and it was highly dangerous. I struggled to keep the car in a straight line even when it wasn't under load and accelerating/decelerating was frightening, as if the shock absorbers had failed and the car had developed rear wheel steering. I threw away the goodish SO-3s on the front, fitting a pair of T1-Rs and everything was back to normal, apart from with Toyos all round the car tramlined a lot less and small bump absorption was better than with a set of SO-3s.

Hopefully you won't have this problem if you are replacing the fronts first.
