3 tires the same...1 different. Is this a bad thing?

*Joey P* · 06-03-2004, 02:02 PM

Okay, I have a 96 V-8 AWD expo. I bought it used from a dealer and never looked at the tire size when I bought it as all the tires were brand new. This was about 2-3 months ago. Today I'm looking at the tires and I realize that I have 3 235/75-15 tires and 1 30x9.50-15 tire! I know that a 30x9.50 tire is not much bigger than a 235/75 but is it bad to have it like this? I know that having a huge difference in size is bad but is the difference I have minor enough? How about on AWD? The tires are all like brand new still and I'd hate to have to replace just a tire. BTW: The tires are BFG All terrains if that makes a difference or not.

If its a front tire it shouldn't matter because of the open differential

*Joey P* · 06-03-2004, 03:40 PM

Yes, it's in the front but it won't affect the AWD at all?

yes, under some conditions it may affect the AWD. It may also add handling, ride, and vibration quirks.

I haven't noticed any quirks but I've only driven it this way from the day I've had it so I wouldn't know otherwise. If I run it this way until the tires wear out will I damage the AWD? I wouldn't think so......and I don't want to get new tires just yet.

i think that would make me a little bit nervous running one size bigger tire,

i think it would be ok to use as a spare cause it would only be used temporarily,

but in my opinion I think it would be best to run all the same size
