Silly and simple question...
Has anyone that has installed "4" 33-37" tires ever had to use a factory spare and need to drive say 100miles to get home and purchase a matching tire again? Just curious what it would drive like. If anyone could elaborate on this it would be appreciated. Thx

 

From what I've read your ESC will think you are out of control and probably lock your brakes up. handling would be horrible and you would have to keep speeds down. I wouldn't do it for ten miles. Maybe to limp off a trail but not on the road.

 

If you had to do that put the odd size tire on the front.

 

That is a brillant answer (common sense prevails!!). Of course I would recommend using a tire of the same size. If price is a concern try to find a used one...

 

I recall 1" diameter diff being the max for short distances. The size diff wreaks havoc on your r/p.

 

Don't do it. I had the wrong size spare on a used explorer I bought because I never checked. I found out when I needed it that it was the wrong size. It was not driveable, and I had it on the front. Every so many feet it would start pumping the breaks hard, especially around turns. I had to pull it over after a couple of miles because it felt like I was going to break something. If the wheels aren't turning at similar speeds the computer thinks some wheels are spinning and reacts. After feeling my jeeps traction control react to going fast over large dips in the road I think it would be even worse than the explorer.

 

This is true. I always get a matching spare for this reason

 

If you are running 35" tires on your Jeep...you need a 35" spare tire ...period!

 

Most definitely get a same size spare even if its a used one. Not only for safety but the esp is sensitive enough. A small spare would probably throw it into overload.

 

Wow never knew that would happen.
