Tyre Dilemma's

Having had 32 X 11.5 X 15 MTR's on my vehicle for the last 2 years and being very happy with the wear and the grip and lucky that they just missed the guards., the you know what hit the fan last week. I had a slow leak in the rear passenger tyre so off to the local tyre fitter for a patch, on inspection the inside of the tyre had cracks all across it, after checking all 4 they were all the same. I had done 38,000k's and when they checked the wear it was about 1/3 so I was happy with the wear but miffed that some really good looking tyres were to be binned.

I spoke to the owner who said they would be warranted and I would pay 2/3 the price for 4 new ones, which was great, now to my Dilemma, Wrangler MTR have changed their tread pattern and the new 32 X 11.5 X 15 has a 24mm larger diameter that the old pattern when new, so end of guard clearance, now I scrape even coming in my drive way under brakes with the wheel slightly turned. So a body lift is now happening in the next few weeks.

My big winge is how can the same tyre size by a manufacturer change so much, I now different brands vary but wouldn't have expected same brand tyres to do it to this degree
