I know there used to be a thread regarding rim and tire sizes but can't seem to find it.
My question is, will a 110/90 tire work on a 1.85 rim on an RD350. I'd like sporty tires for the current build but have D.I.D. rims in 1.60 for the front and 1.85 for the rear. To change to 1.85 front and 2.15 rear would mean going back to steel rims.
The stock RD rims. 1/6 and 1/85, work very well with 90/90 and 110/80 tires. We were required to use OEM stock rims in Formula RD and those are the size tires we raced with and they worked, and looked, great. I am partial to Avon's but there are very good tires of other brands that are a bit cheaper that work very well in both wet and dry conditions.

Thanks Lyn! For the rear tire size did you mean 110/90-18? If not, will a 110/90-18 fit?
110/80-18 is the more common choice
EDIT: spelling typo correction
agreed. go for an 80 profile if you can.
So...it seems that 110/90 is way easier to find in a set of tires; 90/90-18 and 110/90-18. I even have a set of BT-45's right now. They were in the shop and I brought them home for some reason. Maybe the RZ350, but that takes 110/80-18 too, so who knows...
In any case. What would the downfalls be of a 110/90-18 be? What brands of tires would it be easy to find in a set of 90/90-18 and 110/90-18?
80 is shorter and should have a slightly less dramatic profile as a result. It also means shorter ratios. I run 90's, they are fine, 80's are probably fine too. The difference is 10mm.
agreed. its not that big of a deal.
100/90/18 and 110/90/18 on mine.
The bike came with that and I just ordered without checking it here. Wish I had this info before.
Thanks everyone for the input. Looks like I'll run the BT45's I have for now.
@Kandy; the tire sizes you listed are available in DP tires...you're running them on an RD with stock rim sizes?.... Hmmm....
:jacked:
Looking to change out my tires for my RD. Any suggestion on what brand/style I should run?
Can we start a list of 18" tires that are available and proper? I was just looking at this subject online a few days ago. I don't profess to have any advanced insight into what's best. Other people with better knowledge will have to add opinions on quality and personal experiences. Most common I see are Avon and Bridgestone BT-45. The BT-45 were by far the most recommended when I bought mine from several sources.
I hope that the more learned people will weigh in. I am just basing this mostly on a couple hours of keyboard time not trial. My focus was simply finding matched tires available in the most discussed sizes for front and rear.
I am running Bridgestone Battlax 110/80 rear and 100/80 in the front on my RD 350 and I have been happy with the combo. This is apparently slightly unusual with regard to the front 80% aspect ratio. More common is 90/90 or 100/90.
Bridgestone: BT45. They are also available in 100/90 and 90/90. So are BT46 which are apparently a longer wear option.
Avon:AM26. These are available in a soft race compound also. I believe Lyn Garland carries these.
Shinko: 712.
Metzler: Roadtec 01 110/90 and 100/90;
Continental: Road Attack; Conti Go; Continental TKV 11/12 (front has a vintage look); Conti Road Attack 3. An acquaintance (and 2SW member) who's opinion I trust said that the Conti tires are awesome. I believe that he is using an ultra soft compound. If you are a So Cal canyon basher or Appalachian mountain rider they may be right.
I don't like the idea of mixing brands and tires of different series/design. I am sure that there are probably super great combinations possible if you do. I just don't myself. I also don't really care about long life or mileage. I would rather replace my tires multiple times than low-side into a ditch once because my tires were hard. At the same time I'm not gonna put gum slicks on my RD. ...Ok I might if there were any.
We have some pipe and oil threads. Can we make one for tires in the Speed Shop??

Like the idea of collecting tire data.
I ran Battle-axe BT-45 on my 74 RD. Don't remember the exact sizes though. Rear was very tight with stock gearing and 530 O-ring chain, and the front chopped in short order, which I heard others complain of after I purchased. They are great tires, but I am now running Avons and will be sticking with them based on my current impression. :whoop:
i use 3.00-18 (continental) in front and a 100/90-18(michelin sirac) in the rear
I just pulled the (cast) wheels from my 400c to have new tires mounted. The tires on it: front - 3.60 18 Dunlop with 2000 date code (rotation arrow backwards), 4.00 18 Goodyear with 1993 date code! Never run tires old enough to vote! Replacing them with Shinko 712 100/90 18 front and 3.50 18 rear. Both are labeled for the position they are going to. Tire mounting is one task that I don't have the tools/space/desire to do myself.
BTW, the rear did not rub, but it required the caliper to be loosened a bit to get it off. The old rear measured 110 mm at widest and the front 85.

Sorry for the delay in response but I settled with Shinko: 712. I don't have a bunch of experience with a ton of tires but these were much better than whatever were on the bike when I got it.
i have a set of those on the 70 r5, which i rode today. they are pretty good. actually came in via the interstate today, did just fine .
Shinkos seem very good on light and medium bikes. Tend to not handle a GoldWing's weight, though. Does in mean they can't handle speed loading? Don't know. They seem popular on the Dragon, but there really isn't speed involved in 318 curves over only 11 miles. That's something like 4 times the turn frequency of Barber, but you can't carry near the speed through them (even without LEOs). I have Shinkos on my RD400c, but it will never (while I'm on it) see hard cornering or high speeds. They do feel comfortable cornering, much better than I remember the originals back in the '70s.
i actually have some on both my concourses. believe it or not, they do well. even well over 100 . :twocents: are they better than a pilot road 5? hell no. but they are better than they should be.
Shinko 712's unite!
Mine haven't seen much in the way of miles or curves, but are holding up well.
I was gonna spoon a set of the Continental radials on the next project finished, but if folks are liking the Shinkos...many American dollars could be saved for candy and injector oil.
Avon Roadrunners. Which are hard to find for a 110/80 rear right now...
