I need tires.

No, you have to go by the sizes stamped on the wheel. Then check the tire manufacturers website to make sure a given size will fit.

I just bought the Avon roadriders as well.

Very nice, soft tire, more for sport riding, and leaning.

If you don't mind a little labor, installing the tires yourself is a good option.

Most shops I checked wanted $75 PER TIRE....JUST to balance it!
(cause I bought mine online)

I said screw that, did some quick internet research, installed the tires myself!


If you wanna balance them, youtube it, there's some good accurate ways to do it in your garage for CHEAP.

I've heard so much good about Avon roadriders and GS bikes, I'm ordering a set myself this week.

Are all GS Bikes 90/90/19 and 110/90/18?
(I've an 850GD)

No, GS tire sizes are all over the place.

Your bike uses 100/90-19 up front, 130/90-17 in the rear.

You can't go by the tire size, either -- it's pretty common to find incorrect tires mounted when you buy a GS -- some shops will pretty much stuff on anything they have lying around in order to make a sale. Mine was wearing a 110/90-19 up front when I bought it, and the handling improved nicely when I mounted up the correct size.

I ran a Continental "Blitz" on the front of my GR 650 twin, riding in mountainous terrain, and really liked it!!! Never slipped out and braked well for me. Seemed like it was wearing reasonably as well. Bike is now sold.

Oh, had a Dunlop 404 on the rear. It is fine, too.

I just took a better look at the tires ..and surprise , the sidewalls are cracked (dark work area). The tires are Continental F- 3.25 H19 R82 R- 4.25x85 H18 K112 mounted on cast wheels. I am really surprised that the tires are tube type but then maybe I'm comparing the wheels to cars? I will change the tires myself,this will give me an opportunity to clean and polish the wheels.
Now I just need to pick a tire from all the excellent advice.

Thanks

I went tubeless last year, but we had to prepare the wheels first so the valve stems would seat correctly.
Flat with tubed tire: remove wheel, unseat tire, remove and patch tube, install tube, inflate tire, install wheel.
Flat with tubeless tire: plug hole, inflate.
