There are about 20 diff ideas. I ran 18 on one and 28 on another . Both were fine, only got about 14000 out of them. Back to see if newer OEM tire is better, some said it is. Have 28 in it with Ride on installed too. Have kept up with all those I ride with in curves, hills, speed, etc and the tire seems to be great.Only has about 6,000 miles on it though. Spyder dealer said no more installing off brands on Spyders and needed a tire pretty quick. No dealer standarization on tire support, that's for sure.

try 20-25 PSI, with the stiffer sidewalls and less weight on it don't need anything close to what you would use in your car. Have 8K+ seems to be wearing evenly @ 20psi :yes::thumbup::clap::clap:

Same here. 28 seems right. :thumbup: TOM :spyder:

I ran 24 in mine, and it is worn more in the middle than the edges. I now have 20 in it trying to even it out. It is almost worn out, 2/32" left in the center at best. I will run it a little longer. My new Kumho just arrived and when I install this one I will start it at 20 psi.

I've run 30 PSI in mine since I got it - it has worn very evenly. I'll stick with that pressure.

^^ And that might be perfectly alright for you & your riding, road surfaces, loads etc, but it may well be very wrong for someone else riding their Spyder elsewhere, or even if they are riding your Spyder with the same loads on the same roads - the 'correct' tire pressure for a given tire on a Spyder (or any other vehicle) that you are riding depends mainly upon YOU, your riding style, your loads, the surfaces you ride on, and a whole heap of other stuff... and as little as 1 psi of pressure difference can make a vast difference in tire behaviour, traction/grip, & wear/longevity. But what I run in that given tire may well be totally useless or even downright dangerous for you, especially if I ride in a different manner, on different roads, or with different loads!! :shocked:

And the 'pressure recommendation' on the tire placard is no more than a vaguely educated 'best guess' compromise aimed at suiting the widest range of potential riders & loads, surfaces, etc that BRP & the tire manufacturer can come up with. Change from the OE spec tire or the OE spec loads & roads, & while that placard may provide a good starting point for you to work out the 'best pressure' for a given tire, the optimum pressure will invariably be different if you are running a different brand &/or construction tire or have varied any of the other possible parameters!

As a number of us have been saying for a while, altho maybe not in quite these terms - Bigger or more robust air bags (ie tires) need less air to carry the same load on the same roads!

In Aust we have access to the Australian Tyre Manufacturers Handbook which provides a 'start pressure' for the each specific tire size carrying a specified load (I'd guess there is something similar in the States) and from that given start pressure for the specified load, drivers/operators can 'fine tune' their working pressures to suit their changes in all the other driver/load/road specific variables - but there is NOT a 'one size fits all tire pressure' for pnuematic tires, despite what some vehicle manufacturers (who may benefit financially if you only ever use their specified tire size & brand) would like you to believe! :sour:

Thank you Peter for your more factual and less well I guess that will work approach. We can all benefit from the information provided. :bowdown::bowdown::yes::thumbup::ohyea:
