"tire brand recomendations"


  

          

Howdy folks, I am getting ready to replace the tires on my 75 Commando. I have Dunlop K81 4:10 x 19 tires front and back. I ride mostly on 2 lane blacktop mountain roads. I am not a roadracer , but do enjoy laying it down in a curve now and then. I weigh 230 and usually ride solo .I would like any advise on brand , size { what is the size equivilant of 4:10?} and tire pressure. Thanks Steve

Your about my weight so you need to read at least the ending of this. http://www.nocnsw.org.au/tyres.html Talks about the extra weight you can hold with an 18 inch tire. norbsa

Steve,

On my '73 850 Interstate I have 100.90H19 (4.10H19) Avon Roadrunners on both ends. I assume this is the Roadrunner Universal tyre, but it just says Roadrunner on the sidewall.

The '72 750 Combat Interstate that lives at my house has the above mentioned Avon Roadrunner on the back and a 4.10H19 Pirelli Gordon Supersport on the front. The Gordon is about 1/4" wider than the Avon. I have no idea if the Gordon is still available.

I weigh about 210 and I run 24psi in the front and 26psi in the rear, per the Avon webpage and Norton factory recommendation.

I ride a lot in the mountains on the weekends and find this tyre pressure ok. I cannot get the bike to lean over far enough to get within 1/4" of the edge of the tread because of grounding the pegs and sidestand.

The 26psi rear pressure seems to help the tyre last longer. I used to run 32psi rear and 30psi front. The back tyre wore out in no time. Commando's seem to be very hard on rear tyres.

Cheers, Orlin

I'm running a '72 Combat, which I ride fairly hard, and carve some good curves with.

I've switched to an 18" rear wheel for better tire selection. After the rim swap, I first shod it with Avon Supervenoms front and rear. The rear one was worn out after about 2000 miles, which really miffed me, considering how much I paid for that tire. After talking to a few of my sportbike buddies, they put me on to the Bridgestone BT45 Battlax. It has a dual rubber compound, harder center & softer cheeks. So I picked up a 110/90-18 and stuck that on. I've got about 4000 miles on it so far; it still has lots of tread left and is resisting the tendancy to go square. Traction and grip are on par with the Supervenom.

You will see a lot of debate over 18" rear wheels affecting handling, I haven't noticed it. IMO the most crucial (and neglected) elements of Commando handling are swingarm spindle wear, isolastic adjustment, and and headsteady configuration / condition. I built a headsteady with a pair of heim joints and that really crisped-up the handling.

As far as tire pressure goes, I weight around 200lb (being desk jockey / couch potatoe will do this to you) and I'm not running any security bolts, so I run about 35 psi front and rear. On my bike, I found that running the front tire at a higher pressure actually improved the handling (front wheel has more of a 'planted' feeling, improving steering response) and reduced over all vibration.

My $0.02, HTH.

Cheers,

Derek

another vote for the Avon AM18 super venoms. same tire front & rear, 100/90 V19's. At first I was thinking they would be slick until they warmed up, but now they are broken in. the "oval" cross-section of the tire, means you get a better contact patch. Improved cornering and handling. lets see how they wear/hold up
