... Avon tires in general are terrible and should be classed below the Shinko brand.
Nothin wrong with Shinko tires. I run them on nearly everything I have, including the rear of my '99 LT. Yeah they carry a lower speed rating (H, 130mph) but are 79 Load reinforced tires (shinko 777HD). Have 2K miles on the tire now and still looks nearly new. I expect at least 10-12K on the tire and almost all of that is 2-up riding and grinding down foot pegs regularly. For the money, you cant beat that with a stick if thats what I get out of them.
Well I check my pressure every time I ride.
2000 on a ZX10 would be high mileage for a local rider here.
I wish I could get 2000 miles out of a set of tires on any of my sportbikes.
Do you street the bikes or are they track toys? I ride extremely aggressive on my sportbikes, specifically on my RC51, which is a heavy girl. Regularly drag knees and am hard on the power and brakes pretty much all the time unless i see those scary black and white cars around. Only time I have done-in a set of tires that fast is on the track, and then it is just the shoulders and they make for good take-off street tires after that. I also run Shinkos on my RC51 as well (Apex 010 to be exact) and punish the hell out of them and they take it in stride - with a plug in the rear even. I have about 3500 miles on those and showing about 1/2-2/3 gone. rarely will I see 6K out of sportbike tires, usually 4500-5500 miles.
I have trashed a brand new set of michelin pilot powers in 7 laps on the track, but they were soft racing compounds.
FWIW, Im running the shinko 777HD on the rear and an IRC on the front - 41f/42r - max pressures per sidewall, and love the combo now. the front still looks new and the rear is showing nearly no wear and both very sticky on the dry stuff. Wet is another story. Im not happy about that but im not sure if its the tires or the bike as I use the 777 on my metric cruisers as well and have no wet handling issues. The rear seems to be the slippy tire in the rain on the LT but I have no other comparison to base it off of.
dont knock the brand unless you have used them (recently - they used to be junk though). Its another option, at least for the rear of the LT. I am going on a 2771 mile trip, 2-up and fully (over)loaded in 2 weeks (over 8 days) through california and oregon and then down PCH and will report back on that.
