Max tire sizes for a R100RT?

[westonjezek]

Hello!

Has anyone ever fit a 120/90-18 on the front of a R100RT (or similar model)? Trying to figure out what dual-sport tires will fit, and not having any luck finding stock sizes (front: 100/90-18) that match the rear tread pattern (rear: 120/19-18).

In this blog, a person fit 120/90-18's to the front of a R80 monolever: http://bmw-umbau-blog.weebly.com/bmw_bo ... es/03-2017

Thinking about this tire: https://www.revzilla.com/motorcycle/shi ... ring-tires

Any thoughts on if a 120/90 would work for my R100RT monolever, front AND back?

Here is a link to photos of stock tire clearances in front and rear:

I would always recomend using the recomended tyre sizes that is 90/90x18 front and 120/90x18 rear. Increasing the sizes will affect the handling making the bike slower in bends. I doubt you'll get a 120/90 in the front. There are any number of combinations that will fit. I tend to use Metzlers (ME77 rear, Lasertec front) normally but I have Conti Go on at the moment. Seen to be OK but not over impressed with how long they've lasted. I'm sure there will be any number of other opinions along directly. This is a tyre thread after all

O goody, a Tyre Thread. Michelin Pilot Activs in stock imperial sizes for me. Neutral steering, excellent grip and they maintain their shape right to the end.

But I see that you are after something that looks like this:



I guess those blocky tyres will get you to the cafe precinct on a dry day without too much trouble. It's your bike. Have fun.

Thanks everyone for your feedback! We will see if they fit

Checking in to let everyone know that the 120/90-18 fit the front perfectly and a 130/90-18 fit the rear. I went with Shinko 804/805 Big Block tires. Still handles great, if you're not an aggressive rider.
