Cool Tire size

O.k. Guys i'm not hollering it's just my lazy way for someone who is a two finger typest to type o.k.?

Just bought a '11 35is with the 19" staggerd wheels. My question is: Is it possible to go up to 225/40/19 front and 255/35/19 in the rear? I don't need all of the performance reasons why i shouldn't unless they will rub somewhere. I'm an old man and drive like one so not worried about cornering. There are no corners in s.w florida anyway! Thanx for letting me pick yer brains!!

I'm running Michelin PSS 235/40x19 (F) & 265/35x19 (R). Have been hitting the corners, dips and combined corner/dips pretty hard at up to 80 mph to test for rubs with no problems to date. The inboard edge of the front left scuffs the frt wheel well liner slightly when at full lock to the left - as in tight parking lot manuvers. The OD spec for these are 26.4" (F) & 26.3" (R). The 225/40 (F) should be no issue as you'll be a little smaller OD. The spec OD for the 225/40 PSS (F) is 26.1". The ride of the Non RFT's is amazing, no more bone jarring, and best of all no more understeer.

I spent a lifetime in Merrit Is FL, one year - too flat & straight - I can't drive 55!
