Tyre pressure

[Mad-1]

I'm off for a trip soon with a pillion. I'm running on Avon Roadriders and I have 32psi in front and 34psi rear.  What should I increase the rear pressure to for pillion riding?

I was riding road riders 140/70 110/70 and rear pressure of 35-36 psi for pillion/ heavy tail pack and panniers. since moved to bt45's and using same pressure

Ah right, how many miles did you usually get from a rear avon roadrider? I'm only getting around 3000-5000 miles on mine. Thank god they're cheap!

I had road riders on an xj600s thy were bloody awful. Lasted something stupid like 12k though and that's on a bigger heavier more powerful bike than a -1. I'd say you're doing something wrong to get them done in that kind of hurry.

Switch to BT-45s you won't regret it!

Are you riding on broken glass? i was gettin 17 thousand kms out of them, they were by far the longest lasting tyre i've ever rode, the reason i changed to bt 45's and the reason they last so long is because they use a harder compound rubber which takes longer to heat up there for less grip but longer durability. I'm currently getting 9-10k KMS out of the bt45s and they're cheaper than the road riders. You're definitely doin somethin wrong

12k on the divvy was in miles. that's 19k km on a bigger heavier bike, with more hp more torque more weight and only a 130 rear to spread out over.

General consensus on this forum is to stay the hell away from road riders. Michellin do the pilot 2's in a 140/70 i think if you wanted to go for them.

I do accelerate hard on the cb-1, i'm not a top speed kind of rider but I do accelerate hard. Maybe it could be something to do with rear shock adjustment or wear?

[Drewski]

I wouldn't worry too much about pressures as the shock is a bit pushed one-up, let alone pillion I normaly go 2 psi up for passengers in general. 'Might be worth having a look into fitting the early Fireblade shock.

[Mad-1]

Fitted a Pirelli Diablo to the rear now... MUCH more stickier than Avons! It'll be interesting to see what mileage I get...

It's not a great idea to mix tyres either.

[Mad-1]

Cant afford to replace both tyres right now as i only work part time and earn little. But I shall replace the front ASAP.
