Due to a couple of road hazards over the last 10 years, I ended up with tires of greatly varying wear on my Jeep Liberty. They were all Goodyear Wrangler SRA's in 235/70 R16 but two of them were in need of replacement. Sears wanted around $440 total to replace them with two of the same, so I did a little shopping and found I could get two Kumho tires of the same size but rated for 85,000 miles for $280 total so that's the route I went. However, once I got home I noticed what appeared to be a great difference in the overall size of the tires compared to the Wranglers. The Wranglers are both taller and wider even though the sizes indicated on the sidewall are identical.
Is it normal to have big difference in actual tires size across different brands of tires marked as being the same size or did I get some that were mislabeled?
Is it safe to run in 4WD on the beach with the different sizes without tearing up the transfer case?
