I rode mine for a couple of errands. Today, I got the T30
Evo rear tire I ordered. I prefer premium tires, but am experimenting with mediocre rear tires paired with primo fronts. I wear through rear tires faster.
The T30 is heavier, looks larger, and has far stiffer sidewalls than the PR4GT’s and R5GT’s I usually use. I am not sure I’ll be able to mount this manually as I do with Michelin. But I’m going to try.
If T30 is not premium then you should have purchased a T31!
Got 7500 miles on rear T30 Evo GT, 10,300 on current PR4GT which is due. 10,900 on previous PR4GT.
Swapped friend’s FJR rear PR4 at 10,950 miles today for a new PR4. I need to cut a cross section from his tire because there is a ghost image of center tread but carcass feels paper thin. Will have a PR4GT to cut for comparison when I swap mine soon.
T31GT front went 9700 miles, 1000 more than my 2nd best using a PR4GT. Loved the way the T31GT rode to the end, never have liked PR4GT at EOL. Replaced with PR4GT and do not like it new as well as I liked the T31GT worn.
T31GT rear puncture at 3000 miles, couldn’t get it to hold air, mounted my current PR4GT. Years ago didn’t like handling of RS3 set, too light. T31GT set is similar light but when T31GT front is paired with PR4GT rear it hit a sweet spot for me. The PR4GT might be mushy but it is a nice mushy with the T31GT front. Not the too mushy as with PR4GT front.
At the moment RockyMountain has PR4GT rear $170.88, PR4 is more expensive at $179.49. Front is $132.88 for GT, $139.64 not. The T31 rear is same GT or not $128.88, front GT is cheaper, $107.88 vs $110.88.
Say $50 (lowball) to mount+balance then $107.88 + $50 = $157.88 for 9700 miles vs $132.88 + $50 = $182.88 for 8700 miles the T31GT front is clear winner.
For rear PR4GT $170.88 + $50 = $220.88 for 10,250 miles is $0.0215/mile. T31GT $128.88 + $50 = $178.88. Have to get 8300 miles to best the cost of the PR4GT. T30 Evo GT front wore 8000 miles vs T31GT front 9700. Don’t know if that would apply to the rear.
If your cost to mount is greater then a high mileage tire will be a better value. At current prices Michelin and Bridgestone seem to cost about the same to ride.
