I have an 02 Disco 2 with 18 " wheels. What's the largest mud tire I can put on without the front tires scraping? I have street tires right now that are 265/60 R 18 that almost scrape. I need recommendations on brand, model and size mud tires.

 

I think my tires are in my signature but I am on mobile now and can't see it. Toyo Open Country MT and if memory serves they are 285/75. They are too big. I had to get spacers.

So, anyway, that's too big.

You don't mention if you have a lift so I assume you are more concerned about rubbing underneath than fenders, but my with my 3 inch lift the toyo's rubbed underneath. With the spacers they can hit the fender if I turn and hit a bump at the same time.

 

So why "MUD TIRES", by the little you described. your truck is not even set up for muds, like a lift, gears and lockers to handle playing in mud.
