I know the speedo will be off some as the 235's are 29.1 tall, and the 265's are 30.7 tall.
My questions is what backspacing should I look for with the 17x8's? I think all that I found on Tire Rack have a 40mm offset, but list a couple different backspacing. I don't want them sticking out the side of the fender.. or not enough and they rub at full turn.
I would go with a set of BFG AT's in a size closer to stock, but they are not snow and ice rated..
Any help would be appreciated.
Your speedo is going to be off by over 5%. You'll effectively be under-reporting your mileage and you'll always be going a few mph faster than you think. I'd also think that the ride would be "floaty" and soft because of the substantially higher degree of sidewall flex. Also expect a reduction in gas mileage due to the much larger contact patch on the ground...also probably not helping your ice/snow performance. A better fit would be 255/60/17. Goodyear Assurance Tripletred and General Altimax HP (and a number of others) come in that size.
Not sure about the offset. You'd have to get it up on a lift and turn lock to lock to see about the rubbing. 265/65/17 tires are over an inch wider than stock.
