normally on a car tire, worn down in the center like that would be OVER-inflation, but since this is a rounded MC tire, that would be LOW pressure causing a wide section to wear, and wear faster. i run about 2-4 lbs less than the tire is rated for, during summer. remember heat expands everything including the air in your tires~!

never listen to the vehicle manual or vehicle badge. your tires are what matter, listen to them!

Thanks that is what I was trying to figure out if I was running to Low or too High sounds like too low! since the tire is rated at 36psi max ill drop it down to 34psi, 2lbs less then max and Ive had the front at 28 ill go ahead and bump it up to 30psi it will be 6lbs less but its wearing good and, the manual and the scooters badge have a 4lb increase in the back compared to the front so I want to keep that. both rated at 36psi thats what really had me confused cause the front is a 120/70/12 and the rear is 120/90/10! And the Manual has them listed as 110/90's cant listen to it!! But fronts wore great but ill bump it up a couple pounds too and then take the back to 34psi if u guys dont think thats too much psi on a 36psi max cold rated tire?? Thanks alot I will be replacing the rear soon its got a little thread still left not down to the markers yet but very close!!!

Sounds like your gonna hurt yourself overthinking tire pressure. Your tire wore out quick because its a cheap brand, its a rear tire, and its a 10" one at that. You should always use the rating on the tire itself. If it says 36 then your good at 36. The 10-15% below max rating was a suggestion to soften the ride a bit. It sounds like a good suggestion for you since you only weigh 120 lbs.

30psi front and 34psi rear is what I was told should be good thats 2psi less then the max 36psi and 2psi lower then max for the front at 32psi max. Sound good to u guys??? I have been told pretty much by everyone that I was running the tire too low at 30psi when the max is 36psi?

Im making some since of it now! LOL My old scoot had the 13inch wheels not a 12 front and 10 rear so the smaller rear spins more going to wear sooner then the front and 30psi was not enough air. But ur saying its fine to run it at the max 36? But for a little softer ride since I am only 120lbs I think I will run it at 34psi. I have been told 2-4psi less then max and the 10-15% which would be about the same as running it 2-4psi lower then max?

Im going to try out the 34psi in the rear hope that keeps it from wearing quicker till I get a new rear tire asap Thanks to everyone for there help!! This darn Chinese manual dont help at all!! But if anyone thinks I should be running a different psi let me know. I am 120lbs, I got the Bali 250 with a 120/70/12 front going to run it at 30psi and run the back 120/90/10 at 34psi unless anyone thinks otherwise!

Fair , knowing your rear tire is questionable . Every time I would be getting on the scooter it would be on my mind , there is enough road hazards to contend with . Your seeing a potential problem (if in daught air on the side of safety) . A good friend of mine owns a auto repair shop he has the machine that does nitro fill , the main atvantage of nitro fill is it is moisture free so there will be no pressure changes with tempture .

another thing I want to mention is that your weight is low I'm 175lbs -185lbs that may play a part in your tire pressure (for ride comfort)

I have a longbo voyager looks the same as yours 150cc I don't trust the tires in rain or wet surfaces.

I just want to mention when I did the nitro fill when removing the air they vac the tire and the bead broke on both tires a blast of nitro and it poped back on .
