I am going to be adding either 33's or 35's next week and was curious if there will be any issues with my ABS if I need to use my spare (31.92" OD)?

 

if your going to buy 4 new tires thats around 600-800$ right?? spending that kind of cash see if you can strike a deal for the fifth tire.

 

I am buying M/T's so four of them are around $1700. I have worked them down to $1315 out the door and that includes moving my TPMS sensors over to the new wheels so I don't think that I will be getting a spare.

 

I think (not positive) you would be ok if you went to a 33. I would not want to drive very far on it because it makes you differential work hard because they are spinning at different rates. It is kind of like driving on a doughnut. I dont thing you would want to do it with 35s though. If you cant spent the money for tire 5 spend the $45 bucks and buy a AAA membership and skip the spare.

Sorry I was thinking tires not brakes on the last post. In theory the computer will think one tire is slipping because of the different rates of speed. (smaller tires spin faster to cover the same ground) but even if that is the case for the short time you would drive on it I dont thinkn it would cause any damage to anything. (just my unprofessional opinion, take it for what its worth)

 

You'll be fine. Ever seen a car running a donut wheel? Same concept here folks...

 

wow!! 1,300$ man i was way off lol.

 

ya but those are good tires but really high... my buddy had 34's and had to run his 31 for two days and it didn't hurt it... just wouldn't do it long...

 

If you have a limited slip rear differential then you'll want to minimize running a smaller spare. The other option is that if you have a flat on the rear then move one of the front tire to the rear and run the spare up front.
