thanks peter

Some trike manufacturers recommend 20 lbs to 25 lbs. what conversion are you using? I try to keep mine at tire speck psi 32 psi

grampa, my dealer/builder strongly recommended I keep my rear tires around 16-18 psi on my champion kit. I am small, though, and rarely take passengers. He keeps his between 20-22, and often carries his girlfriend with him. If I have the tire spec pressure (as in for the average car), I find the ride terribly rough! As soon as I drop them to about 17 psi, I feel comfortable again!

 

[grampadonut]

checked pressure and seems to be 30 lbs..think will drop to 25 and see what happens....we're still figuring out our new ride
thanks for all the info

I have a Gold Wing 1800 with the same rear tires mounted on a Motor Trike IRS Conversion.....I do mostly 2-up with my Wife, Lotsa' twisties, some straight highway/interstate....I have finally settled on 20 lbs. Seems to serve me well under all conditions and solo or 2-up.....I experimented a lot though....Post Your results.....

I run 17 psi around town. But do go up to 22 when we go on a trip riding 2 up with a trailer on and extra gear.

I have found that the lower range works better than the higher suggested range for me. 20-25 lbs is what the trike manufacturers suggest, but I have found 18-20 to be to my liking on most every trike Ive ridden. (thats cold tires...you'll gain a pound or two when hot) You'll want to experiment and see what works best for you. BTW 32lbs rides like a buckboard to me!

 

[grampadonut]

what about "front" tire
thanks
peter

 

[Nana]

I believe the front tire should be kept at the same pressure recommended for a 2-wheel bike. Correct me if I'm wrong on that!

 

[John Luciano]

That would be around 40 to 40 # on the front tire . i also recommend getting "A" Rear tire for the front of the trike. Get rid of the radial and go bias ply. The tire will be a rear bike tire the same size as you now use on the front .

Grampadonut is running a Lehman conversion on a Street Glide. Nice set up he got a GOOD deal on! Harley sez on front tire for bike, 36 psi. I've been running at 42 -- seems to be more stable in hard turns. Even before the conversion, I preferred the feel of 40 - 42 in the front tire. I also find that at 42 psi, it doesn't build as much pressure on our HOT roads, therefore the tire iself is running cooler.<br />

Hes right. <br />
<br />
BTW, a lot of the newer tires now recommend 40-41 lbs.

Harley calls for 26 psi in the rear. Tire calls for max of 36. I run 30 in my rears. Why? Personal preference. Took me @ 10k to find what worked best for me. Ride is a bit on the stiff side, but mpg is far better. Since I do a large amount of Highway travel, MPG is important to me. I live in rural MN so "around town" isn't what those on the east coast, or other heavy population areas, would consider city riding!

 

[Gorilla]

keystone what is your MPG at that tire pressure?

 

[Keystone]

keystone what is your MPG at that tire pressure?

Interstate is @ 30mpg. That's doing 75 mph or so.

Keeping it under 60 on the two lane roads I can get in the upper 30's, even close to 40, with gas that does not have ethanol in it. With ethanol I get around 35 mpg.

 

[Gorilla]

Thanks, about what I get and I run 24 lbs in the rear 39 in the front.

 

[Keystone]

In the flat lands of Florida this year for bike week I was doing even better.

 

[Boscoporp]

It sounds like we all are pretty close to agreeing to the same thing. I keep 40 lbs in the front MPA and I keep about 23 in the rear but I pull a trailer and ride 2 up a lot of the time or I would lower the rear to 20lbs. <br />
<br />
I don't want to steal the thread but what pressure does everyone keep in their trailer tires?<br />

Nail Pressure, Can you believe it, I hadn't even wore the dimples off my trailer tires and I picked up a 2 inch nail. I run 20# per recommendation of CSC.

 

[Nauga Mok]

On trailer tires, run what ever the sidewall says is maximum pressure for the tire. The only reason we're running below rated pressure on the trike rears is for comfort. Out here in the desert where it's been 110 + for the last week -- well, yesterday was only 109 & today is down right chilly at 105, I've bumped my rear pressure up to 28 so the tires run cooler. When it cools off, I'll go back to 22 because the ride at 28 is pretty harsh.
