Then try a different make of tire and experiment with pressures while monitoring wear.Just one or two pounds can make a big difference in wear.I just didn't pick these pressures or tires out of the air,ya know.Everything was trial and error until I GOT IT RIGHT.

I'm sure there's some, but likely not much in my opinion. However, lower tire pressure does make a big difference in cupping. Depending on the tire, low pressure can significantly increase cupping.  Author  Post     gwight  Chaac Reg.

I ran 28 front and rear on my track bike, slicks or treads.... The pro racers would be running around 20 front and rear Remember that tyre temp is always quoted when the tyre is cold, racers put a lot of physical pressure on their tyres so they run quite hot, which increases pressure, so dropping the cold pressure by 2-4lbs will be equalised by the high temp. Professionals will take their tyre temp up to over 100 degrees.   Mick . . . Keep the rubber side down!!  Author  Post     EnGage  Thor Reg.

I have read the same, but I think it is more than slightly - I believe racers use significant lower pressures to increase the contact patch. This is of course what Dave is after - more contact = longer tread life. I just think one needs to lose more than a few pounds to accomplish this.  Author  Post     davetac1  Thunderbird Reg.

Interesting reading here Link particularly the second last question at the page bottom. It appears according to this that race tyres don't run very low pressures, although there are many variables. I realise that of course that these are very different compounds to what we use. If you click on the tab for tyre pressure recommendations it gives a PDF table.   Experience is something you get just after you needed it 1600,Foran Razorbacks, Meerkat bypass, Dyno tune, real headlight,plenty of chrome,switchblade pegs, Nitron R3 shocks & Ikon progressive fork springs etc. Scorpion Western Low handlebars.

You just hit the nail square on the head Todd!! Thank you!! Dave!!! Actually No..... More contact = more grip = less tread life... I know Race tyres are a different compound, but they don't last more than a couple of races. They are designed for maximum contact and grip. I've used road tyres on the track and chewed the crap out if them very quickly. Longevity is mostly impacted by your right wrist. Pressures and tyre brands play a part but the way you ride has the biggest impact   Cheers Smitty 2013 Matt Graphite Storm, Foran Razorbacks, Hagon shocks & springs.
