Hi guys, This is Christy, aka weecamlass from the old forum (they said I couldn’t use my old name because it contained “inappropriate words” - would that be the first part of the name or the last?) Anyway, after teasing my boyfriend about his failure to buy new tires until it was (almost…

In this case the tires are the same diameter, so it’s not a real big deal. They are a different width, but the ones that are the wrong width are (presumably) the next ones you’ll replace. If you don’t drive like a maniac you should be fine until it’s time to replace them. Russ

Actually, the 185 tires are about 2% larger diameter than the 175 tires, but it should be OK if they are are kept on the same axle. As others have said, put the new tires on the back and replace the front tires with the matching size when they wear out. When you have good tires on all four wheels,…

The smaller tire is about 2.3% smaller in diameter so your speedo will have a 2.3% error; will read high as will your odo when you have the smaller tires on the drive wheels. Verify this by Googling Tire Size Calculator. I ran 155s and 165s on a car until the wrong size wore out; I couldn’t notice…

When you buy tires a store that advertises based on low prices, and you go in saying you want inexpensive tires, they sometimes will sell you a tire a size smaller to keep the price low. That happened to me, but I caught it the same day and returned them for the proper size tire- they didn’t charge…

so it sounds like it wouldn’t do any good to move the drivers side tires to passenger and vice versa? I wonder if the people who owned it before me got ripped off by the tire place, as you suggest. I honestly don’t remember the size of the tires I replaced two years ago, but the old ones are cheapo…

Another question: do front tires wear out faster on a front-wheel-drive car? The new tires are on the front wheels, but the (cheapo) back tires seem to have as much tread as the front ones. Yes the front tires will wear faster, I would put the new tires on the back and replace the front tires wit…

i have a question about tires also i need to replace my 2 tires on the back which are 235 70 15 and i found some tires but they are 235 75 15 if i replace those and keep 235 70 15 on the front would that cause any damage to my xterra?

On a 4 wheel drive mismatched tire sizes front to rear are a problem but on 2 wheel drive there is rarely a problem and then not in mechanical wear of the drive train but possibly in handling and braking but there is so little difference in the circumference of the 2 tire sizes you mentioned that on…

Hello from 2007 I guess. I can’t remember what year the car was, I think 2007 or 8 but on my son’s old Infinity, the rear tires were wider than the front tires by design. I really don’t know why and didn’t seem to affect handling at all, but made tire rotation impossible except for side to side.

Same with my brothers BMW. 245/35-20 on the front and 275/30-20 on the rear. Staggered sizes are fairly common on “performance/sport” cars.

Different tire sizes on front and rear?

The transfer case and both differentials are taking a real beating when in 4x4.
