For discussing and sharing pics of various wheel and tire options for the Yamaha RMAX 1000 2 & 4 seat models.
(Specs thanks to MASSIVEOVERKILL)

RMAX2 1000 OEM Wheel and Tire Specs:
Front and Rear (square setup on all models):
14X6.5 ET34 4/156 Lug Wheels
30X10X14 Tires

RMAX4 1000 OEM Wheel and Tire Specs:
Front:
14x6.5 ET34 4/156 Lug Wheels
29X9X14 Tires
Rear:
14X8 ET48 4/156 Lug Wheels
29X11X14 Tires

( wheel stud size is 12X1.25 mm for all 2 & 4 seat RMAX 1000 models )

Massive here adding wheel bearing specs (both are DAC) and held in my circlips:
Rear are 72 mm
Front are 62 mm

Good thread. The offsets are as follows

6.5" rims have 34 mm offset, translating to 5.09" backspacing with closest matching offset being 5+2
8" rims have 48 mm offset, translating to 6.39" backspacing with closest matching offset being 6+1

Feel free to check my math

I know this was buried in the release thread but it sure nice to have it right on top!

What's the wheel stud size?

Good thought. I will ad that in up top.

Only thing I see is if you want to use a 7" wheel in the rear to replace the 8" you might want to use a 5+2 to keep the rear vehicle width close to stock. The stock 8" is 5.9+2.1 and the closest on the outside dimension is the 5+2 .

The fronts are 4.6+1.9 so like you said the 5+2 is closest on outside dimension but you might need to check the clearance on the back side at full drop and turned to lock since the 5+2 will go .4" farther in than the stock wheel.

Yes. Using a backspace calculator these figures are correct. But using a backspacing calculator there is an extra .5" added for the lip width on each side so on the rear of an 8" wheel width it would end up with 2.61" to the outside. This is why I am figuring with a 5+2 7" wide wheel and going to a narrower 10" wide tire in the rear a 1" spacer will be reqired. I'll find out though.

Post update: Spacers are not needed in the rear of the RMAX4 if going to a square tire setup.

Exactly. I prefer to calulate as you did using measured wheel width. I get the same measurements that you have. Not only will I have the .4" more inside but going to a 10" wide tire in the front over the 9" wide oem tire on the front of the RMAX4 also get an extra .5" there. It wasn't a problem on the X4 though with stock suspension plus Yamaha offers 14X7 5+2 wheels with 30X10X14 square wheels and tire setups on their accessory site for the RMAX4 so again this shouldn't be an issue.

Ok. So something else that I have been meaning to post in regards to the last couple posts as well as just being informative in general. The Tusk Teton beadlocks the I picked up for the RMAX fall in line with most of the wheels out there by not being true to size when it comes to their offset. Most wheels on the market these days seem to be this way. They are close though. Everywhere you look these wheels are stated to be either a 5+2 or a 4+3. The 5+2 Tetons are actually a 30mm offset wheel which actually makes them a 4.68+2.32 wheel. Which means that the backspacing will be almost exactly the same in the front as the OEM wheels. Only a .09" difference over the OEM 4.59+1.91 wheel. Now I don't know what the actual offset of the 4+3 Teton is because I have not seen a wheel or box in person and my internet searches have came up empty but the more information on what the wheels out there are actually sized at is better for everyone. So everybody post up this info. as you come across it.

According to Yamaha's first live stream on the RMAX, the RMAX4 can run a square tire setup (no mention of spacers).

Looking at their upgraded tire/wheel kits, you'll see the same SKU for RMAX2/4

Kit comes with 4 wheels/tires and one lug net set.

Do you know about how far into the video it talks about that. Don't have time to watch an hour long talk show. lol

I still think to keep the track as I would desire it to be a 1" spacer will be ideal. I have been using a really cool offset calculator that gives great visuals of what gains you will get using different tire/wheels sizes. It shows I will get added width in the front but not the back with my square setup without spacers. And with the spacers I will get just a little more width in the rear than the front. Which is what I want.

My math is probably all wrong but a 1/2 spacer would probably be closer however it will still narrower than factory. I'm coming up with .55" spacer needed to make up the difference on two wheels with the same backspacing. 48mm-34mm=14mm. 14mm is close to .55". I may be looking at this all wrong too.

 

[wolvymanx4]

For a perfectly straight track yes but I don't think there is such a thing as a .5 inch spacer unless you use the shim type but then you dont grab as many threads on your lugs. A .5" bolt on spacer you leave too much stud hanging out and it might hit the back of the wheel so it couldn't sit flat. With the setup I plan on running I should be just over a half inch wider on each side in the rear which is what I want. You will never know just by looking at it and it should slide easier in the rear and give more stability. I had my X4 the same way and it was amazing.

 

[therebel19]

I had 1.5 on my x4 so the rear really stood out. I understand what your saying and wanting. I was posting that up for info anyone might want.

 

[wolvymanx4]

Oh for sure. I had 1.5" on my X4 as well and loved it but I also ran a +10mm offset wheel which was closer to a 4+3. The +30mm I am going to run on the RMAX is closer to a 5+2 so I think 1" will be sufficient. We'll see though whenever I get it back. I love the smell of new tires but it's getting old in the living room after a week and a half. LOL

So I got the RMAX back from the dealership yesterday afternoon and installed my new wheel and tire setup first thing. Let me say that I'm very pleased with the results. The fit is fantastic. Exactly what I was wanting. The stance it has is great. It just looks right. Where the tires sit with regards to the fenders is what I would hope to get these days on a new machine right from the factory like the RMAX2 comes equipped. The DOT radials ride so smooth as well. Feels like a truck when taking off or backing up. Can't wait to get them on the mountain and see how they do.

 

[therebel19]

Looks great. That was 1 inch spacers right? Just trying to keep your post up to date.
