Thanks for the input Jim. I appreciate it. You like the Trail front and GT combination?
Can you feel the stiffer sidewall and stiffer construction of the GT over the Trail? My biggest concern would be mixing tire stiffness like that.
I've used both the "Trail" and the "GT" on my 2014 GS. The Trail wore out faster. I felt no difference in grip.
I tried a PR4 Trail and got less than 4,000 miles out of it. Amazing tire, but I'll definitely get the GT version when I go back to a dedicated road tire. I've had several people tell me that they can't tell the difference between the Trail and GT, other than the mileage. I ride a '15 GSA and ride about 2,000 miles a month.

That combo - trail front and GT rear is what I'll use from now on. To be honest I was worried about the stiffness of the GT as well, but I could never discern any difference. Others with more sensitive receptors can chime in but I couldn't tell the difference. Go for it, you will not regret it.
I ran a rear GT and got the same mileage as on the Trail but slightly harsher ride. Using Trails since then.
All fantastic answers. Thanks everyone. I greatly appreciate it.
Maybe this requires a whole new thread, but I think for discussions like these, where people list how many miles they got out of a tire, it would be helpful if they could post a picture of the tire they felt was at the end of its usable life.
I've noticed in tire threads the WIDE disparity in mileage individuals get out of a set of the exact same tires, on the exact same bikes. Yes, riding style, weight, application all comes into play, but even when these variables are similar, you still see pretty good spread of data points.
For example, it's been stated before that some replace their tires as soon as they start to square off a bit. That could be at the halfway point of a tire's actual usable life, depending on where you ride. One picture I saw posted earlier mentioned a tire having a little life left, but compared to a few of the tires I've replaced, it looked like it had many more miles left in it.
Either way, some reference as to what the tire looks like when people post their mileage might add some context to the numbers.
Get the harder one. TC will keep it in check.
I too am currently running this combo. I can't feel any harshness or anything weird from the harder/stiffer/whatever compound rear tire. The wear and handling has been first rate so far. (about 7k miles almost all road) Funny enough, on the few occasions I took it onto dirt roads, I liked it better than the stock A3.
Fair point. I wear mine down to the wear bars / indicators imbedded into the treads, but that again depends on how far down into the wear bras your want to take it before swapping them out. Could vary as much as 1K miles. Unfortunately I did not take any pics.
Bah, humbug. These aren't super sensitive race tires. Tire wall stiffness or not isn't nearly as relevant as the tire pressure...
When I have the extra money to always have a couple sets of tires, I will be getting the trail on front and get on back. Being how they're designed you won't notice a huge difference besides the mileage. When you lean the bike both gain more grip.
I had the regular pr4's on my previous bike and loved them. When rain hit it was as if water wasn't there at all. That and the mileage of the tires were amazing.
I started this thread a couple years ago. I've gone through my second set of PR4Trails. I'm at around 7,600 miles and the rear would be just okay for local daily rides but I wouldn't take it on a trip. I've been very satisfied with the wet and dry performance of the PR4Ts. But I'd be ok with getting more miles out of a set of tires.
My bike is a 12 GSA so I can't use the GT version but the standard PR4s do have a rear tire that fits. I'll still need to stick with the PR4 Trail up front. Is anyone running this combination?
Also, since the PR4 series is a few years old isn't it likely a new version should be due? Are there any rumors put there?
I run that combo on my V-Strom. I wouldn't say I got that much extra, if any, out of a regular PR4 vs a PR4 Trail. You save some money going with the regular PR4, though.
I have a 2010 GSA. I've tried the standard PR4 rear vs Trail. Remember that regular PR4 got a compound update from PR3, 3 was soft-med-soft and PR4 is med-hard-med. However, the Trail didn't get that compound update (I feel we got a bit ripped off) so it's soft-med-soft, but being Trail designated, apparently suited to our big bikes.
I'd say I'm getting up to 20% extra life (can only compare over a couple of each - and there are still many variances). It's hard to prove, but I could swear the regular profile is also more curvy than the trail. I say this because I was off the edge of the Trail rear, with x amount left on the front. On the regular rear I'm pretty much on the edge, but the amount left on the front tyre has decreased... Grip wise, totally happy with the regular, which technically is a bit harder with possibly less grip.
Very happy with Trail front and regular rear combo and will keep doing it.
To quote my own post: I'm now up to about 8500 miles on these tires and the rear is getting flattened and will need replacement in the next 2000 miles or so, The front still looks great. So I estimate that with my type of riding I'd expect about 10 grand out of the rear and the front at least 15? grand, maybe more, maybe less.
Will put on my second pair of PR4 Trails this weekend. Very happy w/ them, have never felt so comfortable in the rain before these tires.
