Modern Buddy

What is the correct tire pressure for the 170? The manual says 25 PSI rear and 22 PSI front cold. However, the sticker on the scoot says 30 front 30 rear. I've noticed a big difference when I put them at 30 PSI... It feels as though the suspension is non-existent and the kidneys take a beating! Is it personal preference or is there some reason that Genuine says one thing and PGO says another?

If you go by the 30, then you will get better gas mileage but it is going to be a harder ride. The manual is based on what is going to be a more comfortable ride, which is what you experienced in reverse. If you are anywhere in between those you will be fine, so find what works for you.

I keep mine at 30, I am pretty hard core when it comes to gas mileage. : )

Your tread will last longer if you keep 'em at 30, also

Ive heard 30 rear and around 25 front makes for a good ride.

to be ultra technical. The tire pressure should go up about 10 percent from cold to hot...If it goes up more...You are underinflated, less you are over inflated...That being said...I run 30 in the rear and 25 in the front...smoothes out the ride a bit, and tires are cheap

When I got home yesterday I dialed in 30 on rear 25 on front, and my ride to work this morning was VERY NICE. I was running 30 on both.

I'll do just the same. It feels very firm and I feel every bump and groove in the road. It gets old real fast, and I need some relief.

Hope you like it. I think it was jijifer that said she always changed her front tire to less that 30 when she gets it back from the shop.

Your Fly 150 has bigger wheels though. Thanks for the input but we were talking about 10 inch Buddy tires. 213lbs muscle huh? Big boy. Im 160 lbs of pure animal rage!

Why do you have so much rage in you?
Do you ride like this?

I ride with rage, you ride on meds.

'Roid rage'. As for the tire, I just go with whats written on the tire.

How big a gap is there between the Genuine-recommended pressure and that "maximum" number stamped on the tire?

The stock prima's say max 30. The genuine sticker says 30 front and 30 rear while the PGO manual says 25 rear and 22 front.

Mine came from the dealer at about 35 apiece. 30 rear and 25 front are my new mantra.

I had the same question for my new 170i. It took me a while to find this thread so I thought I'd bump it up and ask if anyone else has recommendations regarding Tire Pressure for the Buddy.

The Genuine sticker in the underseat cargo compartment says 30 front and 30 rear. The PGO manual says 25 rear and 22 front. It sounds like anywhere between those numbers is acceptable and a common recommendation on Modern Buddy for a balance of ride comfort and fuel economy is 30 rear and 25 front.

I saw a thread on the Blur forum about the effect of tire pressure on maximum speed, I assume that also applies to the Buddy so for riding on a highway I assume it might be better to go with a tire pressure towards to higher end of the acceptable range.

On my 170i I was riding around with about 22 front and 25 rear. Just tried 28 front and 30 rear. Stiffer but nicer. I prefer it personally. Less sluggish, more precise and responsive. I found it perfectly comfortable too. I weigh about 175 lbs.

I have been running 40 psi on front and rears and I think the " harder ride" is not that hard. Just my pref

Make note of how short the life of your rear tire is.

We started this way years ago and about ran our first rear tire bald about 1800 miles. Then asking around, we dropped to much less and have ended up about 24/28 front/rear and seems to work great with two scoots going well over 10,000 miles for the front. Still never over 5,000 on the rear!

We have never gone as low as 22/25.

I bought the scoot, from another member, with the K61's on there When i bought it he said the tires had roughly 500 miles on them and I put another 2900 on them they were just starting to hit the wear bars.. I am sorta anal about tires and for how cheap they are. figured why not.

I also have a top case on my scoot and I know that adds to tire wear.

I wholeheartrdly concur. Scooters are rear weight biased. 25 lbs of air in the front smoothes out the ride quite a bit with no measurable loss in performance/handling.

I usually go 2 lbs above what the manual says (24 in the front and 27 in the rear); come time for winter storage I will increase to 27 in the front and 30 in the rear since the tires lost pressure with lower ambient temperatures;

at home I use a bicycle tire pump to slightly overinflate above my target pressure and adjust by releasing air in small bursts until I get desired pressures; on the road I try to use gas stations with digital pumps that the pressures can be preset prior to inflating the tires;

I have run both and prefer the 30/30. Seems to handle better and gas milage is excellent.
