what tires sizes fit rx3

[fishman10]

ok, much has been discussed about what tires are available...what im wondering what other ''close sizes'' will fit an not cause any clearance issues.

[SpudRider]

I installed a Shinko 244 tire on the rear wheel; it was size 5.10-17. I mounted a Kenda K270 tire on the front wheel; it was size 3.50-18. Both tires are working well for me.

I bought both tires from Rocky Mountain ATV/MC.

Here are some other sizes which fit the rear wheel.

5.10-17
130/80-17
130/90-17
130/70-17
Here are some other sizes which fit the front wheel.

3.00-18
3.50-18
100/90-18
110/90-18
100/100-18

Spud, just for giggles, do you think a 4.10-18 would fit on the front wheel?

Yes, I certainly do.

[Weldangrind]

That would be an interesting look, but I doubt that it would be a benefit.

The stock front tire is size 100/90-18, which is essentially a size 4.10-18, tire.

I'm surprised to hear that the stock front tire is so wide. That's the standard size for most dirt bike rear wheels.

You are exactly correct. The front rim is size 2.15-18, which is the same size rim for the rear wheel on my Honda XR650L! The Zongshen ZS200GY-2 comes stock with the same front rim.

That is why I prefer mounting either the Shinko 244 tire in size 3.00-18, or the Kenda K270 tire in size 3.50-18, for the front wheel of the Zongshen RX3. Both of these tires are narrower, and much lighter, than any of the other knobby tires which will fit the front wheel of the RX3.

Spud, why narrower (3.00-18) for the Shinko 244 than for the Kenda K270 @ (3.50-18)?

You can certainly choose the wider Shinko tire, but I like the dimensions of the Shinko 3.00-18 tire better. I like the dimensions of the Kenda, K270, size 3.50-18 tire best.

Well thanks to the many post in this thread and the others I was able to replace my OEM, CST tires with the best I could get here in Iloilo City, Panay, Philippines; not exactly what I wanted but the best I could do here.

Since the OEM, CST brand tires suck (IMHO) and my selection of tires here in Iloilo City is limited and after much shopping around and calculating I settled on a Fuji Tire, Wing 2000, Trail Sports, 3.50 - 18 and a Samsun (they seem to be related to Dunlap somehow), what they call a Dual Sport (no model name or number) Series in 140/80 - 17 but has a pattern like the Shinko 705 for the rear. They are both larger in diameter than OEM and I was concerned more about the rear due to lifting the bike and making the already bad seat angle worse. It turned out to not be as bad as I'd thought in height; it is higher by about 3/4" and I'm only 5'6"". The traction was much better right off and they are not broken in yet, only 40 Km today in the rain but got on a good stretch of mud and gravel, felt much better than OEM. I forgot to measure the ground clearance before the fit and after (the best I could do with my helper) looks like 7 3/4" at the center stand bracket and 9 1/2" at the skid plate, that will do for my riding.

I might need to get a pair of slightly longer legs...

The RX3 is an adventure bike, not a MXer or Dakar racer. Therefore, the RX3 should have tire sizes suitable for its intended use use. The sizes fitted are well suited to the bike's intended use. The rear tire has a slightly shorter cross section but otherwise same size as the KLR650. The front tire is about the same size as experienced and knowledgeable KLR riders switch to and giggle like little girls first time they grab the front brake on gravel, and instead of a washout the bike just stops. It is one size smaller than what is typically fitted to more roadworthy adventure 650s, which is perfect for a bike that weighs 100 pounds less than the 650s.

It ain't broke. Don't try to fix it. If you want a 21-inch wheel, get one attached to a MX or trials bike that can make good use of a 21-inch wheel's characteristics.

Stock front is 100/90-18. 100mm is ~4.00. A 4.00-18 will be about a perfect replacement, just a tad taller, roughly equivalent to a 100/100-18. Anything from 3.00 (90) to 4.60 (120) will fit the RX3 front rim, but the extremes might assume some odd cross section shapes. Putting a flat-topped rear knobby on the front that is at the extreme high width for a rim size throws some round across the tread, resulting in more predictable handling on hard surfaces. Just because a tire fits the rim doesn't mean it will fit the bike, or have sufficient load capacity to be safe.

The stock rear tire is 130/70-17. 130mm is ~5.10. A 5.10-17 will be about the same width, but quite a bit taller, roughly equivalent to 130/100-17. If someone will post the width of the rear rim I'll post the sizes that will fit the rim safely.

I would prefer to see TW200 tires on the RX3. Monster traction has spoiled me. Unfortunately, the TW's Bridgestones are speed rated slower than an RX3 will go, and the Shinko TW replacements are speed rated even slower. If I can knock the lens off a TE's taillight standing it up at 35mph, I'm not worried about saving a pound or two of front tire weight. I'll be running the biggest tires I can fit. I like traction.

Keep in mind that different types, makes, and models of tires can be marked with the same size and actual measurements can vary significantly when mounted. Most manufacturers have actual sizes listed on their websites if you go hunting.

Did you mean to say TW? If so, that's impressive.
