New tyres, new pants ?
Discussion
I have just replaced the rear tyres on the Griff with the same, that is, Bridgestone S02. The previous had about 1mm tread at the centre a bit less at the edges but it handled well (even in the wet).
I have changed nothing bar the tyres (at 23psi – hard walled) and the car is handling like a bugger. Camber grab is understandably more so but the car now feels like it wants to wander at anything over 60 and feels very light at the front end. Fast curves and the car feels very unstable, like the rear end isn’t following a clean line through. It’s a battle to keep it straight under hard acceleration.
Leven checked the alignment, rims, types etc. the car is generally Ok at slower pace.
Very strange – anyone else had this ?

I've heard that some tyres (Toyo') can often take a lot of bedding-in, and upto 500 miles to scrub-off the release agent. Not sure if this is the case for the SO-2's.
The other thought would be with the age of the new tyres. SO-2's have been discontinued for a good few years (replaced by SO-3's which are also now discontinued) so have these new old-stock tyres gone hard in storage?
All seams strange if nothing else has been changed.

The Surveyor said:I had this with my new Toyo's - a good 3-400 miles before I felt happy, but that was in the winter - I expect it will be sooner this time of the year. They needed 'curing' before they felt ok.

Steve Heath describes the process in the latest 'Bible'. It entails making them work a bit (just by a bit of 'spirited' driving until they get warm), then letting them cool down, repeating the exercise a few times.

Their advice is to take the tyres out of their rapping and stack them on their sides in a warm room for a month. I did this and found my Toyo T1-S’s were superb needing only a couple of hundred miles to scrub in. I know one example isn't statistically proven but it worked for me.

I contacted Toyo myself whilst I was experiencing this phenomenon and they were (understandably) reluctant to acknowledge that this problem existed. However, after a few hundred miles like you have said, all's well!
Call me daft, but surely renewing the rears is always going to make a difference anyway. When I got my new rears earlier this year it took a short while to learn how the car behaved (in fact the back-end is much less likely to break away - I'm more likely to be drifting all four tyres).
Groucho,
Needed some fronts for mine, and couldn't get hold of the SO-3's anywhere, they are still listed on their website, but the list is over 12 months old. Every supplier i spoke to said they were discontinued?
Heard mixed reports about the Toyo's, so put some F1's on and they feel great.
