Tire size?

Stock front on my 2008 is 90/90-21. Will Kenda K760 trackmaster II size 80/100-21 fit?

Stock rear on my 2008 is 130/80-17. Will Kenda K760 trackmaster II size 130/90-17 fit?

YES.
90/90-21 equals, First number of tire size, 90 millimeters. Second number of tire size /90 is 90 percent of first Number! Equals 81 millimeters. -21 is the rim size!
So a 90/90-21 is 90 millimeters wide, 81 millimeters tall and fits a 21 inch rim.

So, 80 mm wide, 80 mm tall, 21 inch rim. Yes it will fit!

Trakmaster IIs effective off-road; surprisingly versatile on pavement, except: Front may wash out during severe lateral movement on hard surfaces. I discovered this characteristic, trying to recover the roadway after an on-coming UPS truck forced me toward the shoulder at 60 mph, as though the truck driver wished to play "chicken" with me.

Thanks.
Hope I don't run into that problem but it's good info to have. I'm looking to put some more aggressive tire on for about 6 weeks next March. There are some good rally's around here in the early spring and it's always muddy in east TN that time of year.

I run big block knobbies, TKC80s in 130/80. Although stock sized, they rubbed on the muffler, which had to be shimmed out. Not much, maybe 2-3 mm in washers. Give that a look when you get your trackmasters installed.

I agree with Bill10. I think you can go with just about any tire...just as long as they clear the muffler and frame. I have found that a couple of well placed washers, and maybe a longer bolt or two will help any tight fit challenge.
Go with the best calculated fit, but once they are installed, check the clearance! Then make your adjustment(s).

Tire pressure question

Hi All,
New to the Forum and posting my first question. I have a 2008 KLR and just replaced the stock rear with a TKC80. How can this be? I bought the bike last year with only 1,000 miles on it and have a little over 4,000 miles now. Anyway the manual says 20 psi and at the shop they put 33 psi in the TKC. Sidewall says 35 psi cold. I assume the pressure varies by tire brand so the info in the manual doesn't apply to the TKC? I'm planning on replacing the stock front soon with a TKC80 as well. Any recommendations otherwise?
Thanks! Mike

Geeesss, hard to imagine that no one has replied to your question.

I'll recommend to always run +2 PSI in front tire verses the rear tire! Why, you may ask?
Because 70-80 percent of your and your bikes total weight can be on the Front tire with proper braking and especially when going down hill.

So I'll recommend 32 front / 30 rear as a Minimum for asphalt usage, for almost any brand / model of KLR tires.

I agree with Paul unreservedly! Many will say to run higher pressures in the rear but it isn't necessary unless you are carrying a load and the more rear pressure, the smaller the contact patch.

That said, I run 22-24 front and 20-22 rear 'cause I ride mostly offroad and I'm too lazy to air up and down all the time.....if I was riding the slab, I'd definitely go with the 30.
