CV boots are simply pliable rubber dust and dirt covers to prevent contamination of the constant velocity joints. The boots also contain the grease within the CV joint. Size of tires will have no effect on them.

This is a bit extreme. A dealer would need to show that your modification caused the failure. Oh sure, they will say not to modify anything, but they can't blame a faulty A/C unit on the fact that you put wider tires on your car for instance.

As far as excess wear, you might be putting a modicum more pressure on the bearings if you alter the wheel offset, but you wouldn't see any effects of this for over 200k miles.

As far as speedometer and odometer, you are taking about a 1-3% difference in diameter. Instead of going 100 mph, you will really be going 97. Really not much to worry about IMO.

Yup, stock 2011 Limited 17's, fit fine. Love them, just took them up to South Lake Tahoe without chains.

No rubbing issues. Even turning all the way.

Jeez. This is what I get for asking about car modding on a weenie car forum.

I've been lifting and 4X4ing and real trailing my Toyota trucks for years and I've lowered and resprung etc my cars forever. If you're careful and do things right, you're going to be fine and usually better than stock. Stock is meant to be conservative, soft and mainly cheap to produce. Aftermarket parts and tuning are nearly always better unless you do something wrong. Bigger tires when going from stock 265 to 305 like my FJ, yes, to you put more strain on the hubs axles etc but you learn to accept that for the better performance where you want it with that vehicle. Off road. Subie needs to be better in snow and rain and on the road. Slightly wider tires that are a much better tread and compound should help out quite a bit.

Where did you find these? Tire rack isn't listing that size.
