Where can I get a tire this size?Been looking all over and can't find one.I've got a 2.15X12 coming for the rear but my front is a 1.6X12 and I would like to put a 90/90 on it.What should I run on the 2.15?

scottiedawg66 · 06-17-2008, 12:37 PM

120/80/12 is what I read on supermoto junkie. Seems like you have the right idea for the front. I cant find any SM 12"s right now, most seem to be back ordered untill tomorrow. I will post up when I find something.

I just got a set of the IRC MBR-750 tires. 100/90-12, 12/80-12 they look nice and are supposed to work really good

patman · 06-17-2008, 09:23 PM

Is the 100/90-12 OK for a 1.6" wheel?Where did you get them?I've used the IRC 10's (I'm using one right now) and they work great.

We run 100/90-12 on 1.85 and 2.15, should be ok on a 1.6 but the shoulder's gonna fall away and narrow the contact patch. Racing or cruising?

patman · 06-17-2008, 09:51 PM

Just cruisin' on my street legal mini.I'm going to end up with some thing that is way too big for my 1.6 because it appears no one on earth makes a 90/90-12.Most of these little tires are way too expensive so I'll get a couple tires and mount 'em up.If they aren't exactly how they should be then that's just the way it'll have to be.

firepower354 · 06-17-2008, 09:54 PM

I just double-checked and we do have one on a 1.6. Looks fine. I was thinking of the 10" bike.

patman · 06-17-2008, 10:06 PM

I'll probably end up with a 110/70-12 up front and a 130/70-12 in the rear.I don't know how it'll work out.Probably Kenda K413's or K761's.I may have to get a 2.15" wheel for the front too.

I would not put a 70 series on any of these rims. The tire rolls over bad. Use a 100/90-12". It works pretty good on the 1.60" rim. Cheng Shin makes a 3.00-12" C131. That is a 90/90-12" and it is cheap, real cheap........... Cam

patman · 06-18-2008, 12:24 PM

Cheap is good.Cheap junk is not.And I'm having trouble finding a 100/90-12 too.

What do you consider a fair price for a 100/90-12" tire that you are willing to get on the highway with? Cam

patman · 06-18-2008, 01:03 PM

I don't ride the highway,just the city streets.Right now I'm running a Kings brand rear tire,and an IRC Jetty MB38.Both work great.The Kings was kind of spendy,the IRC was cheap,but is of very good quality.

patman · 06-18-2008, 08:50 PM

How about a 110/90-12 front and rear?

I'm trying to go that route right now. Two questions for Cam and others: 1. will a 110/90-12 fit on a 1.65 rim without rounding the profile off too much? 2. will a 110/90-12 fit between a set of chinese USD forks?

1. When we only had 1.60" x 12" Excel rims, we all mounted up 100/90-12" tires on them. You will have a small portion of the tire not used. This is the most inexpensive way to get in to mini road racing. USE A HEAVY DUTY TUBE.
2. Not sure what the width is on your forks........ The triple clamp dictates the inside width. KLX110 Marz USD forks are very hard to get a 2.15" x 12" rim and 100/90-12" tire to fit. If you use the 1.85" x 12" rim, it will fit easier. You need 4 1/4" inches between the "bells" of the forks, where the fork seals and dust covers sit.......

I measured this morning and I have exactly 4 1/2" between the bells of my Chinese USD forks. Now I'm more worried about my 110/90-12 fitting between the forks than I am about a 110/90-12 profile on a 1.65" rim.

True the rim in the front forks to make sure it sits EXACTLY in the center. You should be ok. Cam

patman · 06-23-2008, 10:01 PM

I'll probably end up trying Vredesteins front and rear.That is if they are available.
