Getting ready for new tires on the R27. I have the Heidenau K34 on my R50 and I like them but I also like Coker tires on my vintage cars. I found this Coker Classic E70K online and was wondering if anyone has used these and what they thought.

Thanks!!!

James

The only thread that mentions Coker tires is this one:

Size?

The tire looks OK and the price is not too bad, especially since it's Coker, but they don't seem to have the correct sizes for /2s.

I have never owned a Coker

I have never owned a Coker motorcycle tire but I have had their classic car tires and they are very poor. The consensus among the classic car forums that I follow is that anything made be Coker is pure junk and downright scary to drive on. There is even a popular saying among those of us with vintage Corvettes, Friends don't let friends drive on Cokers. Their car tires are famous for uneven construction that makes them impossible to balance and scary at high speeds. It is possible that the motorcycle tires are OK, but I doubt it given their long standing reputation.

Concours

The car nuts I know who are interested in shows buy Cokers because they look authentic. It's important to have bias-ply tires. Most of those cars are rarely driven in ordinary circumstances. Your comment about the quality is interesting. The prices are often stratospheric, and that's why the relatively low price of the motorcycle tire surprised me.

Yeah, I agree about the car

Yeah, I agree about the car show guys who never drive their cars so the tires are just for show. I drive my old cars so I will not go near a Coker tire ever again.

Online or Shop?

@ Jambo

Might I pick your brain as to where you are picking these tires up at? I am in the market for some new rubber for the summer and would like to know. Thank you.

RevZilla

Hello,

I got mine from RevZilla because they do a lot of tire sales and you can be guaranteed they are fresh. Price is good and the shipping was free. They got here in great shape and the date code is very fresh.

I don't really know anyone

I don't really know anyone personally that has Coker's but they do have that "look" all the car show guys like. Probably best to "show" only if you are talking about 2-wheels. Safety has to be more than looks if you really ride your bike.

About the Heid's... a fantastic long wearing road tire but be forewarned that they have one really odd quirk... they will scare the crap out of you on any type of "rain grooves". Open steel grating on a bridge too. The rear-end will squirrel away/back-and-forth under the calmest of throttle. I'm okay with it now because I know and can be prepared to gingerly control the bike.
It may be a combination of the bikes fault too because it is being mated with a tire design from that era.
Like why BMW finally extended the wheel base on /5's in 1973 (LWB models). Say this with all seriousness and you can look this issue up on this or other forums.
If I am planning a trip where I know there are going to be sustained rain grooves (by me that is the Tappan Zee Bridge) I'll make sure to navigate a completely different route. Or just ride another bike.

I have a set on my r60/2. Ironically from MAX in Brookfield too (great dealership and shop). I can't wait for them to wear out but at about 4000 miles on then they still look new, have hardly worn at all and look great. If you do get them it's just good to know ahead of time so it doesn't surprise you when something like that comes up. Construction groove too.

I have Heidenau K37's on my Ural sidecar rig. Fantastic off-road tires. Really a tough tire to change if you happen to do that yourself. Sidewalls are like steel.
Couple pix of Heids on my /2 and a new K37 on the Ural before and after a "pusher" (rear drive wheel) tire change:
