TSO,
I also thought it was a 5% tolerance but there many out there with 215/45/16 front and 255/40/17rear which measures out at 5.98% with no problem?!?

That's becuase it's not how the 5% rule works.
You take the ratio of the stock front tyres to stock rear tyres, ie the 'standard ratio'.
Then with whatever tyres you get, the ratio of the new tyres has to be within 5% of the ratio of the stock tyres, ie the 'new ratio' has to be within 5% of the 'standard ratio'.
If your fear of staying alive, outweighs the thrill of making the corner, brake.

Sorry Kevin, but without sounding a bit below the avearge IQ, then 215 45 16 (stock fronts) and 255 40 17 (upgraded rears) should be ok as SS stated? Thats on stock oems 94+ 16/17s combo.

Just to be pedantic....do you mean 5% of the 5% (if the stock ratio is 5% for arguement sake)....ie +/-0.25% .
215/45/16 and 245/40/17 ratio is 4.67%
215/45/16 and 255/40/17 ratio is 6%
225/45/16 and 255/40/17 ratio is 4.43% (current)
225/45/16 and 265/40/17 ratio is 5.75% (?future)
As you can see, there is more than the 5% of the stock ratio (+/- 0.25%) change yet the cars are OK?!?

Currently running 215/40/17 upfront & 265/35/18 outback on a '95 targa without any TCS or ABS problem, and well tested at track too.. Using Kumho MX which have been great on track and reasonably priced.....

Just had 255 40 17 GY F1 GSD3s rear tyres fitted, they stated their guide for that particular tyre & size, recommends 33 PSI, but when I questioned this, they stated this is only advisory!? My previous oem 245 BS RE010 was 40 PSI, but I know when you go wider, it normally means less PSI is required. Is 33 psi about right guys for those with GY 255s or any other 255 tyre brands? Cheers
