And I just entered my 2006 FJR, Michelin recommends both the PR4 and R5 for me. Given what I’ve read above, I’ll pass on the R5’s...
There are a lot of tires better than the R5.
Bridgestone T30 and T31 are very good but lasts about 3/4 of a PR4. I didn't mind the OE BT023 rear, it lasted as long as a PR4GT but costs nearly as much.
Thought Dunlop RS3 were too "neutral".
Metzeler Z6 is inexpensive, rides good, but front lasts 3/4 that of a T30 or 2/3rds as long as a PR4GT, and rear wears even faster. Have plugged many tires but the rear Z6 was the first that felt like it tore when I pushed the plug through. Mounted a T31 when I got home.
Shinko 016 is easily the fastest wearing and worst riding tire I have used.
Using RockyMountainATVMC prices for comparison a set of PR4GT costs $350 and T31 GT costs $230.
Looking up specifics I got 8700 miles of my front PR4GT and 8000 out of T30 Evo GT. The PR4GT is $155 and T31 GT (guessing it will wear same as T30) is $105. Add $50 mounting and balancing (I do my own) the PR4GT front costs $23.56 and T31 GT $19.38 per 1,000 miles.
The rear PR4GT is $199 for which I got 11,000 miles. Rear T31 GT $124 (oddly cheaper than the not-GT) for which my T30 Evo GT got 7500 miles. Add $50 again for mounting and balancing the costs are $22.64 and $23.20 per 1,000. This time the PR4GT costs less per mile but not by much. I think 7500 miles is easier to get out of the T30 Evo GT than 11,000 out of PR4GT. Jury is still out on my new T31 GT. Probably a set of PR4GT will follow the T31's. But perhaps not if Bridgestone throws in another $60/set rebate again.
