Coker tires

I haven't really noticed any of these mentioned on other threads, but it's another option for REs. I have no idea about the characteristics of them but they are used a lot on vintage machines (cars and motorcycles) and Hardleys

Also, they mention tread life warranty, but I see no mention of what the tread life expectation is.  I wonder is it for auto tires only?

I find it frustrating - all auto tires seem to be tread-life rated, so at least you have an idea, but for moto tires, it's just the mileage you heard somebody say they got.

I know different riding styles cause different wear, but even so, some baseline comparison, even between models from a single manufacturer, would be very handy indeed...

 Mattsz, take my word for it, auto tire wear ratings are not even close to reality. The company i work for produces vehicles with several different tire sizes/brands/ratings. They all have certain characterizations but wildly varying treadwear ratings 260-520. And guess what? They all wear out at roughly the same mileage. At our place we usually just know that certain brands will grip well but go off early, or others will last but be harder to balance etc. So when we have an unsatisfied customer we can steer them to the brand that will suit them the best( what do you mean my noisy tires aren't covered by warranty? :o).

Thanks, roverman, for knocking all the steam out of a good rant, that was just getting started!  ;D

Still curious to know what Coker has to say about tread life.  I went to one of their pages which shows a 19" tire that would likely fit our bikes, and was offered two choices: just buy the tire, or add $10 and get a "special" warranty which apparently guarantees against premature tread wear - but I found no hard numbers...

Even if tire tread life could be measured, I'm not sure motorcycle/car/light truck tires could be measured the same way.  Some motorcycles are ridden so infrequently they more likely to rot than wear out.  My tires are still the stock set, that's 12 years old.  I'm suspicious of them, but they were hardly ridden (I've put more miles on the bike in 6 months than the PE did in 11 years) and it was garage kept in AZ.  They seem pretty soft and good tread, but now with 5k miles and 12 years, I'm going to switch them out.  No telling how much longer they'd go though...

I put a few miles on these today.  The handling is different than the old Avons. They seem to make the bike feel more agile and have consistent feel from 10 mph to 60 mph. I am running a 3.5 x 18 on the front and a 4.0 on the rear. (18 psig, 24 psig).
I kinda expected to slow my handling compared the Avons, as they are roundish compared the the triangle shape of the Avons.

The tires are Phonix cycleE70p and are made in Taiwan.  They mounted up fine and air up to 70 psig to set the bead.  I did not balance them and don't feel like I need to.

Looks very similar to the Dunlop K70, for a very similar price.  I'd be curious to know how they compare in handling, and longevity.

azcatfan, I hear what you're saying about tires aging, but I'm simply referring to tire tread life, not tire life in general.  I'm not worried about the rubber rotting if I can't get a year out of the tread.

I know it's hard to say how long a tire's tread will last, depending on its use.  I've got K70's front (3.25x19) and rear (3.5x19); although they're interchangeable for our purposes, they're both sold as front tires, IIRC.  The rear is ready for replacement after a few thousand miles, but I'm hard-pressed to find any noticeable tread wear at all on the front.

Just wishful thinking, I guess...
