Avon Cobra PSI

[Fishbein]

I've got about 500 miles on my new Avon Cobras. I've been running them at the factory setting for the stock bridgestones: 36 front 41/2 back. Anybody find a different setting they like better? Fish

Run them either at, or close to, the maximum pressure written on the tyre. If the ride is too hard, and your suspension is set up correctly, you may want to drop a pound or two on the back tyre. You will probably have problems with the front tyre cupping if you run at Triumph's setting.

+1

If your static sag is more than 15mm and the ride is too stiff you may want to ADD rear shock preload to improve the ride quality before reducing the pressure.

I like 42psi cold front and rear for max. tread life.....drop to 40psi front if doing a lot of twisties.

I agree with Ogre on running the standard pressure labled on the tires no matter what brand name they are.

I find that 38lb in the front stops the cupping. I have 15,500 Km on my rear Cobra so far. A lot of the km's two up with saddle bags & luggage. The best mileage yet from my eight rear tyres.

I get pretty much the same mileage out of either tire although my last one got cut short from the drive trane locking up at 80 mph which drug a large flat spot on the rear down to the steel belts. Hey it could have been worse but at least I was able to ride her out and keep her upright

i run mine at 41psi on front and a c/t on rear

Run them either at, or close to, the maximum pressure written on the tyre.

Have you read up on the MAX PRESSURE-10% theory. Interesting.

Back when the Cobras were first available for the R3T I emailed Avon about using them on the R3T. I received a response from their Customer Service department with the following:

Recommended pressures are
included below for a solo rider between 170-180 lbs. if you weight closer to
200 lbs or ride two up then you will want to inflate the front to 38psi but
leave the rear at 44 psi for all use.

No. Elucidate me.

I was pointed at some comments on one or two forums. I wont bore you with them - as there was a lot of BS to wade through (you know a bit like the DS wars on here).

But it turned out that on a lot of CARS (yes CARS) the optimum pressure always turns out to be approx Max -10%. This from guys who do track days as well as use their beasts on the road. Most get improved mpg and mp/tyre) without loss of grip or wildly accentuated uneven wear patterns. I've not looked to see if any bike groups have tried. It may be pure coincidence - but it's worth a try imo.
