Proper Tire Pressure???

[NancysToy]

I have a RT SE5 and tag on side of belt states 15 plus/minus 2 front and 28 plus/minus 2 in rear.

I do not recommend running less than 15 up front. The sidewall states a 15 psi minimum. That is seldom done unless there are safety consideraions from dropping lower. Most riders find the handling better with slightly more air up front. Around 20 seems to work well on the RS, and 17-20 on the RT. Try more than 15 up front some time, you'll probably like what you find.

I am running with 20/30 and find that to be fine. However the real difficulty lies with getting any measurement or refill on the rear tire of my RT because of the stem placement. I have a compressor that I can use to fill the front tires but not the rear one! The stem points so that you have to reach through the belt drive wheel just to get to it, if you go to the other side the stem will be pointing away so not easy to get to at all!

Others with same experience? Any ideas?

For me 20psi on the front and 30psi in the rear works best. :doorag:

I agree with Lamont. 20/30 works best for me.Shocks at #4. My dealer concurs on this setting

Different pressures for solo vs 2-up? Street vs canyon carving?

Having browsed this thread, and settled at the "standard recommendation" of 18/28 f/r as a baseline for my RS. What is the adjustments for riding solo vs 2-up & loaded down? Also, regular commuting vs spirited canyon carving? On my bikes I generally turn up the preload and add some air for loaded touring, and drop several psi when running track days. Does the Spyder react similarly to tire pressures?

I've been looking at that and thinking on my next tire service, I will replace that valve stem with the right-angled stems you find on BMWs and Ducatis. Only I will point it towards the brake side and not the belt side.

I'm 1/2 with Lamont, 30 in the rear of my wife's :spyder2: but 15 up front.

2010 Rt 18/28 works great for the wife.

Tire pressure is not normally changed on the Spyder. The wider, flat tires are not as sensitive to the extra load as motorcycle tires can be. BRP does not specify different pressures for carrying a passenger.

18 front 27 rear

First thanks to all who have been so encouraging regarding my "turning" issues. Many wonderful suggestions.
On to tire pressure......for their convenience, my dealership sets all three tires to 20psi. I am wondering what the experienced Spyder RT riders are doing.

I am looking for better turning, tire life, better mpg......

Appreciating your assistance in advance!

I use 18 psi in the front tires and 27 psi in the rear. I also use nitrogen to keep tires cooler and reduce leaks (nitrogen molecules are larger). My rear valve stem is no problem. I just go through one of the sprocket openings on the left side.

Isn't air around 80% nitrogen anyway?

So eventually you end up with just nitrogen as the tiny oxygen molecules escape...
