Hey guys I'm trying to figure out whats the widest that i can go on tires with a stock 1999 jeep grand cherokee. Thinking of getting some nitto tires in december. Anybody other recommendations? Thank you.

 

look up a company called interco the make super swampers check the model thornbirds out they are bad!!!!

 

I will do that. Do you know how wide can i go with my tires? Exact tire size if so please.

 

I would say 30x9.5x15.
edit, sorry, thought this was for an xj.

 

I believe it's a 26570/r16 which is around 30.5 inches
but you will get some rubbing.

Here's a tire conversion calculator http://www.miata.net/garage/tirecalc.html

 

hey, dropping in from the XJ side! howdy yall! as for width, you can go pretty wide, but back spacing needs to be increased as well as wheel adapters if going real wide. if stock, then my 235/75r15's with wrangler dura tracks will rub my drivers side LCA at full lock and when really flexin i can rub up around the flare at top of wheel well. (the flare for where the coil sits) but its not that bad.
i use this a lot:

I totally agree they are bad...terrible actually...i'd say the worst swamper ever made.

 

I'm running 255 70/ 16 on mine. They rub the inner fenders when turning sharp.
It's at stock height and have been meaning to put 2" pucks in and I believe it'll
clear.

 

Sorry to bump up a post from many months back, but I felt it was best to ask my question in this thread instead of creating a new one.

I see that the max tire size people have recommended has been the r16, so is it not possible to put r17 tires on a 1999 Grand Cherokee Laredo?

 

You can.... but WHY....

 

Because the tires on them right now need to get replaced and someone near me is basically giving away a set of 245/70-R17 tires. Would I be able to use those on the 1999 Grand Cherokee Laredo?

 

I'd pass.. But hey I wouldnt ever want a mall crawler so its really up to you.

Make sure those *****ez spin if you get them though.

 

Sorry for the noob questions but what is a "mall crawler"? And thank you for your help man, I really do appreciate it.

In this case meaning a Jeep thats just used for showing off driving on all cement.

 

I had 30x9.5 tires on my 96 ZJ, just a tiny bit of rubbing at full flex. Though it has the factory "Up Country" suspension package which is about 1" lift.
