? on tire press for rear auto type tire.

[txknight67]

For those of you that have put automotive type rear tires on your :spyder2:, what tire pressure do ya run? I just got mine mounted and balanced today and I think they put 35psi in it because I have about a 1 inch section of tread on each side that isn't even dirty yet.

I was running 35 in my G-Force.

Did the full tread hit the ground at that pressure?

I run 35psi in my Toyo T1R, works fine for me.

Thanks

Thanks for the reply's. I am wondering about heat build up *not now obviously*:roflblack: if I run it with too little pressure. The way it is now it won't wear evenly. I will check the pressure, then go from there.

On a little different note, what has anyone done to correct Can-Am's gross oversight of the placement of the rear tires valve stem?:gaah:

 

[SpyderGirl]

I'm running close to 40psi, but I ride two up frequently.

 

[WaltH]

I run 35 psi in my gForce. It seems to be working out okay.

What brand, style, and size of tire? Too wide of a tire on too narrow of a rim can cause this.

Auto tires can hold upwards of 2 k pounds, If the tire your using doesn't have a flat surface the whole tread is't touching the ground. I'll bet at 15/20 psi. it still won't touch. Look at a stock tire you'll see they have a flat surface. Old school = Too much air center tread wear, Too little air side tread wear. The Spyder is a whole new ball game. very Little weight on the rear tire. When i snow plow i use flat surface tires.

Ditto on the valve placement!!

What a pain to check rear tire air! There must be a Can Am tire gauge in the accessory catalog that I haven't found yet. :gaah:

Your Not Kidding. Rarely :gaah:it seems does that digital guage catch a Full reading? I normally put my small compressor on it and it tells me the amount of pressure in it and sometimes I just let it run a little to bump it to 29-30.

I'm with ya on all that. Still think more tread should be hitting the ground. Ya can also tell too much/too little air by looking at the tread from the front or rear of the tire.*very easy to do on the rear tire with the :f_spider:* Too much/convex, too little/concave.

Luckily I had inherited an "old school" slider pressure gauge from my dad that was on a 45 degree angle. And even with that I played :cus: getting a good solid reading.:gaah:

Wow, others have reported running the GForce without noticing this. A good belted radial with a stiff tread, like the GForce, should not do this even at slightly elevated pressures, IMO. Guess when the time comes I'll cross that option off my list. Part of the problem with the Kenda is tread distortion at speed, and resulting wear in the center. I'll be surprised if you don't have to wear the tread flat, no matter what pressure you use. A belted tire that is distorted usually stays distorted.

I let a little air out of it yesterday and it is meeting the road allot better now.:thumbup: I still haven't checked the pressure, just going by the Mark I eyeball seeing how the tread meets the road.

I wouldn't cross it off your list, just make sure the pressures are right. I've seen this phenomenon even with LT tires. As little as 5 psi too much and it wears the middle out.

 

[WaltH]

I am running the gForce at 35 psi.

As a result of this thread, I put a flat ruler on edge across the tire and a flashlight behind the ruler. The pattern of light coming through, or not coming through, indicated that the tire was wearing evenly across the entire width of the tire. This was true until the outer edge where the rubber curves downward.

There are 16,400 miles on the tire and it is looking good.

Tire pressure...

When I changed the wing over to a Falken 512 I realized I could lower the pressure to 32 psi. The M/T had to be pressurized to 41 psi and carried less load than the C/T. It was hard as a rock when riding. The C/T carries substantially more load at 32 than the M/T did at 41 with a much smoother ride.

As I've gotten older and no longer do high performance riding I like the comfort of a nice smooth ride. I could not get it with the M/T at 41 psi. I'm also into "real safety" and I didn't feel I was getting it with the $300 M/T. Since I no longer do high performance riding I don't really need the rounded M/T.

If you are a high performance rider on the curves "it is wise to use the M/T on the two wheeler"... on the three wheeler "use the best traction and temperature rating you can afford". Get that extra margin of safety.

Ride 'em safe! /Ken

Yeah, the valve placement isn't ideal, though I don't struggle as much anymore. Get yourself one of the Accu-gage air gages, it's a must have; the clip attachment for the valve makes it REAL easy and you can fill the tire while it's connected. Here's the one I have:

EZ-Air Tire Gauge
Model# EZ02
Here's a pic, first one on URL: http://www.getagauge.com/

Be sure to get this one, it has a thumb release for the connection. You press the release, slide it on, then let go... it locks onto the valve. To disconnect, just squeeze the thumb release and pull off. You'll find quite a few accu-gages, but this one is by far the most useful; the one with the thumb release.
