Tire Size & Active Handling
Forgive the newbie question and I'm simply without the time to do the research myself at the moment...so I thought I'd post a question I'll title "Tire Sizing and Active Handling for Dummies".
Question is - will I have any Active Handling issues with the following rim & tire configuration?
285/30/18 - BFG KDW NT
295/35/18 - BFG KDW NT
I would like to use some tires I have laying around and just want to make sure I won't have any problems.
Thank you for the help.

So, I'm assuming that means I'd have no problem with the following configuration either...
275/35/18 - BFG KDW NT
295/35/18 - BFG KDW NT
Thanks for your help.

You might well have a problem with this setup. The delta in overall diameter is only about 0.2". Recommended minimum delta is as stated 0.5". Try it and see. Some cars are more forgiving than others. Also it might work for a while but for some as yet not well understood reason, rear tires on these cars wear more quickly and it could suddenly become a problem. And if it does become a problem you just put it in Competitive driving mode every time you start it.
I meant 275/35, not 285/35...
275/35/18 - BFG KDW NT
295/35/18 - BFG KDW NT
What does your math say the delta is with that setup? Thanks again for your help...

I've decided to just throw some 295/35/18's on the rear and use the 285/30/18 KDW 2/NT's that came on the front. The math says that's a 1.3" delta. I should be good to go. In the future I'll go with the 275/35 and 295/35 setup.
Thanks again for the help fellas.
I just wish there were more matching front/rear street tires available in larger sizes for 18" rims! Seems I have to go 275/295 or jump all the way up to a 335 rear in a matching set of street tires! 335 is too big (sticks way out past the fenders) and 295 is a bit too small for my 11.5" rear rim (looks a bit stretched). Optimally there would be a 305/35 or 315/3X rear, with a matching front available.
Finding the right matching set of street tires for my 18" CCW's has been a PITA!

I want a 35 profile, but I can't find any matching street tires in these sizes! If I have to go 285/30 & 315/30 then I'll just get the Yokahama's. They at least have a treadware of 180.
