I know this question has been ask many times and I don't want to beat a tired horse but! Can someone set me straight on the correct tire pressure for my 2012 RT Limited. Stock tires always ride two up can't get spyder out of the garage without the boss on the back but thats ok thats why we bought it anyway.Checked the owners manual it said 15 to 17 which seems low to me then checked whats in the front tires now and it said 33 lbs which seems high. Went and bought a new digital pressure gauge and it said 32.5. Have read several post on this subject and there all different. So now I am really confused. Bike handles ok like it is wife and I just cruse around on it nothing crazy just enjoy the ride but was just checking the tire pressure the other day and now its got me wondering.

Your owners manual tells you exactly at what pressure they should be set at. Front 15-17 psi and back 28-30 psi. When in doubt read the manual, then ask us:)
don't always believe the manual

it was written by geeks who more than likely never rode one in their lives
Yea, sometimes a slide rule will lie... 15psig is just too mushy.

I tried that whole 15-17 psi thing when I first got mine...
It was just way too soft, and I could feel the sidewalls rolling over in the turns...
I bumped it up to 18 psi, and have been real happy with the setup...
The rear is another story...
I'm running 25 psi in a Kumho Ecsta (car tire) The OEM Kenda wasn't bad at 26 psi, but it wore out the center tread section in about 7000 miles...



Thanks,dndfindley for telling me to read the owners manual! If you had read my post I stated I checked the owners manual but their suggested pressures seemed low to me! That is why I was asking in hopes of getting what other riders were using in their tires and not to be insulted by someone telling me to read the owners manual then ask! But thanks

I have run as high as 26 on the front of my RS and pretty much everything in between. Settled on 20 in front and 28 in back that gives me the handling and ride quality I like. With the RT being heavier I would run at least 20 on the front.
Thanks corybud, Thats the kind of answer I was looking for!

Personally i would choose somewhere between 20 and 22 for the fronts on the standard tires, 28 on the rear. Which is what i've done. Nice overall balance to me.

I agtee. I just did the same on a new one. 20 up front, 28 on the back and is a different bike. I think anywhere between 20-22 front. 28 rear is optimal for me, plus the front shock set to 4 or 5 and the rear to about the 4 level. And that'lthat'll be good enough for me alone or two up. It's all a personal preference within the parameters.
I agree with Paladin and several others. I tend to run all of my wheeled vehicles a bit higher than recommended, just to avoid the mushy feel.

A trick I learned from a tire dealer…Load vehicle in the configuration/weight used most often. Have someone draw a chalk line across all tires, then take it for a ride, after a few miles, check the lines, if they are all worn off evenly across the tires, the pressure is good.

Other opinions may vary! :)
I just checked my fronts and they were 15 and 18. Made them 20 and the ride was greatly improved. I was thinking of going to a stronger sway bar but may not need it. Way less sway at this pressure.
Count me as a 20 and 28 guy too. There is a vendor out there that has a very cool tool called a 'dual filler.' Makes it easy to fill or deflate your front tires equally. I don't know what the rules are for mentioning products which is why I didn't give you a name or company. Someone else might mention it or private message me. Probably not hard to make your own as well. I also agree with you, if someone is going to be a [*******] about replying or telling you to read the manual, which you clearly did anyway, just keep quiet. :mad:
Doing research on my wifes 2016 RT, She has switched to car tires and asking the same questions.
So thanks for the kind response.
Tire pressure

According to BRP and the MOM, the front tires are supposed to be 18 pounds. The rear tire is supposed to be 28 pounds. This is for the OEM tires. I run 20 to 22 pounds in my front tires. They are still the original tires and they have 30k on them. The rear has been replaced twice. I got 15k out of the first and about 12 on the second. I have since put on a car tire and run 33 pounds in it. This tire is fantastic! I will never go back to an OEM tire. I get great mileage on it and the traction is very good in all weather. This is an off brand tire that my mechanic found.

Some time ago I found my front tires were feathering. I increased the pressure and that problem went away. I also have found the bike rides better as well. So I would say this, put a bit more air in the OEM tires. They will last longer and ride better.

I too think that the OEM fronts track better with a few extra pounds in them.

But I have to ask: How did you arrive at that pressure for your new rear ?
Typically a "car tire" is thicker and stiffer than the OEM and if anything should require a bit less air to keep a good contact patch.

Went to the BaJa Ron sway bar and love it, It makes all the difference in the world on my 2019 Spyder RT Limited.
Hi DrGizmo. Wanted to welcome you to the forum from North Carolina. Glad you decided to join us.

Unfortunately you have awoken a thread that is years old so might not get any responses. It is easy to miss the original posting date. We have all done it.

Haven’t heard any bad reports of the BajaRon sway bar. I have one sitting in a box out in the shop. Gotta get my lazy butt out there and install it.
Just got new tires for my 2017 Spyder RT yesterday. I had a hard time finding a dealer that had anything approaching "fresh" tires. One Ride Now franchise offered me tires that were a year + past their DOT code... I passed. Finally found a set at Ride Now Phoenix that were 6 ish months past the Dot code so went with them. My owners manual says 28 rear and 22 for the fronts but that was from 7 years ago. Now the dealer insists that while 28 for the rear is fine they put 18 in the fronts. Said they will wear and ride much better. I went with the Kenda Radials {$395.04 mounted and balanced with new valve stems OTD} and these are supposed to be a big improvement over the older Kenda's... we'll see. After one short test ride everything is fine and I do see significant improvements in the ride and handling but need more miles to make a better evaluation. To that end we are heading out next week for some serious riding that should tell the tale... Film at eleven!

:cool:

What exactly are Kenda "Radials" ? Kanines ??

You should NEVER run the tires on any vehicle below the recommended pressures.
The original ones performed better with a couple of extra pounds but still poorly.
