In the process of having some new chrome wheels put on my 06A and figured I would put a new Avon on the rear tire as it will be close to changing once the wheels finally come in.

Thanks to this forum I saw the sale over at Rocky Mountain (RockyMountainATV.com ) for another 10% off. I was thinking of upgrading from a 180 to a 200 rear wheel and there are speed rating differences but wondering if there are any other differences between the VR and ZR?

Anyone have any other thoughts about moving from a 180 to a 200?

Thanks
Jake

I've done it, along with many others I'm certain. It's relatively easy to modify your inner fender struts/saddle bag mount to accomodate the extra width. It does give the ass end a more filled look..

There has been much debate on whether or not it is necessary to just modify the fender strut/saddle bag mount or remove it all together. I'll let you be the judge on that one.... Personally, I thought it was best to leave the strut and just trim potential areas of contact. The link below can be a guide to show you the area that you may need to trim.

I didn't have any plans of installing the factory saddle bags (as this link illustrates) so I actually cut the "squared" section that the saddle bag mounting bolt passes thru completely off.

i've both removed the struts and then added them back in later. They do provide support to the inner fender, which is a support in itself. After putting it all back together I no longer have a tail light popping out because the rear fender shakes around on bumps.

my advice, grind down the edge of the strut to clear the tire but leave it all bolted up back there

Confused

It looks like some in the forum are for modification of the frame bag mount and others have said it is not necessary. Is there a hard and fast rule that it must be done, or should be done??

Thanks

I would not install tires rated for less speed than the manufacturer recommends. There is a reason tires are speed rated.

I would also recommend leaving the fender struts in place. It takes some effort to knock off the high spots, but those struts are there for a reason.

There is no black and white, bro. It is all subject for debate, but my opinion is just as V-Kit stated about the struts providing the inner fender with support. I honestly feel that the fact that it serves as a saddle bag mount is secondary with its primary duty being the support for the inner fender. If I recall correctly, it only took about 4 or 5 beers to cut/grind the clearance for mine and I didn't even go thru the trouble of removing them from the bike..

I, Like many others, removed the supports and have no issues.
On another note, If you have an aftermarket 5 gal. tank, a 200 Avon will rub the tank, a 200 Metz will not.
I found out the hard way !!!

Speed Ratings

On the Rocky Mountain Site it lists the speed Ratings as
Size: Speed Rating: Load Rating:
180/55ZR18 W (168 mph) 74 (827 lbs)
180/60HR16 H (130 mph) 74 (827 lbs)
180/70HR16 H (130 mph) 77 (908 lbs)
200/55VR18 V (149 mph) 79 (963 lbs)
200/60VR16 V (149 mph) 79 (963 lbs)
250/40VR18 V (149 mph) 81 (1019 lbs)
300/35VR18 V (149 mph) 87 (1201 lbs)

But when I go through the checkout process the 200/55 comes with just an "R" indication which is pretty significant decrease in top speed capabilities.

200/55R-18 (79V) Avon Cobra AV72 Rear Motorcycle Tire
Regular: $313.21
Our price: $185.99
Part# 1245150004

Ok mid point crisis here...stick with the 180 ZR or the 200

True....no time at 149 but it is the designation change that worries me from VR 18 in the main description but just R when I go through the checkout. Don't spend much time at 106 either but earlier some folks mentioned sticking with manufacturer speed recommendations.

Am I over-reacting here?

That 79V load rating is a very high load rating. That's the rating required for my BMW K1200LT rolling elephant. I don't think that's the right tire.

that's 160 lbs of just extra metal, fiberglass and plastic - sounds like a lot to me, and feels like a lot when I change rides. Check out the maximum loading of both too. The LT is pretty beefy and pays for it with a lack of tires available because of the required load rating - and none of those tires are great IMHO. There is only one radial the rest are bias ply to meet the 79V requirements. Amazing though is that the LT handles like a dream after you get it above 5 mph.
