Wheel and tire time

There are better suppliers than Central Wheel.

Original rims were 19" wm2 front and rear, if you want 18 rear then I would go 19 wm2 front, 18 wm3 rear.

Ok, after much debate and even more research, I've narrowed it down to this. Front and rear is staying 19. After looking over my front wheel, its seen better days. Since I need to get a rear anyways, I'm going with two new wheels. Ive narrowed it down to this.

19 WM3 front and rear with Heindenau 100/90-19 on both
19 WM3 front and rear with Dunlop TT100 4.10-19 on both

Without getting into the weeds of which will help me defeat Valentino Rossi, LOL, either one of these should work, correct?

Been going through the same discussion on this thread (again), and @gortnipper has a good tabulated list of possibles on page 2. https://www.accessnorton.com/NortonCommando/tires-for-a-newbie.41834/

Agreed
Devon Rim Company do better quality OEM style rims, chromed or stainless.

Devon rims was founded by this guy who sold the company but still does wheel building to high standards and could get hold of good quality alloy rims.


Also they do not advertise but these guys come recommended too

If you switch to 18 inch, go for 2.50 rims, not 2.15 ( wm 3)

I have:

100/90/19 front on WM2
110/90/18 rear on WM3

As far as the look of 19 front/18 back goes, the proportions look good enough to me... but I also am mounted on cast alu wheels, so I'm don't have the stock wheels look anyway.

The rolling circumference of my two different tires with different rim sizes is close enough to be virtually the same circumference...

As far as rim sizes and tire choices go, the idea of a wider rim is to have a wider tire for a greater contact patch area, but to also keep the sidewall flex down to a minimum so it improves both the precision of handling and tire's grip area on the road. When they say a tire is optimized for a certain rim width it means that the tire's intended shape is created on that rim geometry. A lesser or greater width rim changes the resulting shape of the tire...

By the way, you should get aluminum rims because the lighter unsprung weight of your wheels will improve the performance of your suspension..... and therefore improve the handling...

I totally understand everyone’s reason on recommendation to 18 rear, but I really want to stick with 19.

Either of the above will work, correct? My research says it should, but just want to confirm.

I never got on with TT100's, followed white lines too easily and over rippled tarmac I felt like the bike was going to fall over but others find them fine. With the Heindenau I would go 90/90-19 on the front for an 850 for the quicker steering it gives as the 850 has the revised front end angles to slow the steering down and a thinner front tyre will negate some of that without getting twitchy like on a 750.

My Combat came with Avon GP 4.10-19s that had a much rounder profile than the TT100s. When I tried the TT100s it felt way more unstable than normal. I've had Avon ever since. I guess next time around it will be the Heidenaus.

Couldn't agree anymore .. New , the TT100 worked fine but it didn't take long before the rear tire squared off leaving a horrible feeling every time you leaned it over . Replaced with 19" roadriders and never looked back

19 WM3 front and rear with Heindenau 100/90-19 on both
19 WM3 front and rear with Dunlop TT100 4.10-19 both.

Noted the recommendations and reviews, but will these combos fit?

I have had 4.10 x 19 Dunlop TT 100 on my Commando front and rear and been very happy with them. The only negative is wear on the rear but I can live with that . I am not a boy racer but I don’t plod either and have had some unfortunate interactions with the agents in charge of determining what is an acceptable velocity for a 70 + year old man on a 50 year old motorcycle. I live on a barrier island and must transit a bridge with rain grooves on the concrete deck and also encounter steel gratings on my rides - tracking is detectable now and again but has never been worrying. My earliest experience with motorcycles as a boy was in the woods of the Pine Barrens in Southern New Jersey and in the sugar sand fire roads you quickly learn to let the bike move around under you . Truth be told the more modern tires may be better but for my level of riding ( and it seems you may be the same) the TT 100 are fine .

yes. Graham
