Please help me choose a tire!

Thanks wicastawakan for posting your review of the Kumho Solus KR 21's. Good stuff.

I think you're going to like the BT Tech Stiffening Plate and Strut Tower Brace. The handling improvements from the Strut Tower Brace are more dramatic and noticeable than from the Stiffening Plate, but I'm glad to have both on my car.

 

One thing I failed to include was tire pressure. I run the front at 42 psi & rear at 40 psi. The vehicle/tires seem to function very well there. No tendency to bounce, chatter or emphasize road imperfections to the vehicle/driver. If a concern, I think the 40/38 combination would be sweet.

 

You posted this some time ago but you seem to be still in thius thread
I checked on line with Goodyear, no deal. Sent an email and after the 2nd exchange, Sue at consumer relations understood what I was after. She said it is 853.06 rotations, in case you want to be that precise
By my calculations the circumference difference is .6". And by rotation is less than a 1% difference.
