Best Tyres for the Honda ST1300

from an st1300 Pan European using the GT version of the BT31 tyre front and rear

dry grip - great if smoothish, found slightly rough (UK B roads) had a little bit of a skip feel on even shallow bends)
wet grip - good compared to past but have had better from sports tyres.
road feed back - sometimes a little too much. feels like a slip when it isn't sometimes. but great feed back on what you want too
handling - I'm no racer but can have a good spirited ride with the sports bikes and keep up fine. Normal road surface and good weather a large bike handles well
comfort - great, but could also be the bike to be honest
buy again - YES! about to buy another set now! 11500 miles to a rear (although destroyed it on the last 100 mile) and the front is still legal! (just). I would never ride a tyre beyond the legal limits but the rear went from 2m reminders to a middle section missing in 100 mile. I cant complain at getting over 11000 miles before it was a problem. change before the limits and you will still have your monies worth! and it was still gripping like a good tyre. I also don't potter about so it took a beating.

I used the EXEDRA MAX (Radial), which is better than the bias ply version, on a Honda ST1300 while riding around Australia. Two up and towing a trailer full of camping gear at 100+km/h, the rear tyre lasted the 8,000km from Townsville to Perth, via Broome.

None of the Sport/Touring tyres from any brand that we have used during the last 15 years have lasted much more than 6,000km while touring and towing the trailer behind our CBR1000FS or the ST1300.

Brilliant at everything but picks up every - and I do mean every - possible puncture out there! And when they get a puncture, it's almost always at an angle so is irreparable. And don't think it was just bad luck.....I've had 9 rear punctures this year and only 2 of them could be fixed. Yes, that's right, I've had 7 pairs of tyres - both pilot road GT3's and 4's inside 1 year! Seeing as I do the same roads year in, year out and never had anything like these problems on other brands, I can only put the blame on the design.
Totally not cost-effective. Never again! Gone back to the much cheaper Avons.
