I am changing to tubless rims
If I fit the wider rear is it straight fit
or does anything need modifying

Wider rear?

Presumably you mean a wider rear (tubeless) rim to suit the use of different aspect ratio tyres. It's probably a good change based on the tyre choice/availability alone!

No doubt you're aware that this will also effect overall gearing.

There may have been discussions on this Forum, but all that I know is that 110/90 x 10 may rub on the 'inner' crankcase face as may 4.00 x 10 on the bump stop.

No doubt you're aware that this will also effect overall gearing.

How can it affect the gearing when the rolling diameter is the same ?. Just asking lyke

The rolling radius of the wheel will be the same, but if a different size tyre is used the overall rolling radius may change and alter the final gear ratio.

Thanks for. The replies
I will just put same standard size front and rear

Sorry!

I didn't mean to put you off, & in racing, the specials classes have used wider rubber on the back for years.

However, you have the consolation of precise interchangeability, front to back.

It's ok
I've ordered a pair of wheels .
Then I started thinking about the wider rear. Would it make sense to go wider rear as I can still change the order .

wider on back for me more rubber on the road need to use a spacer to keep away from crankcase

if you keep the alloys/steels the same but place the larger tyre on the rear then there's no mods @ all except for the stud replacement if using SIP

Not Sip, Af Rayspeed

no mods then buddy

You will need longer studs on both hubs if using AF tubeless rims, on wide or standard

Not correct for standard width. No stud mods req.

Got my rims and tyres today
Supplied with tall dome nuts and 2 different washers
Cannot get the front on not enough thread

Thats why I posted my comment - I had the same issue, change studs to longer and all good

I may order a wider rear then I will have a standard rim as a spare.
Does the 350.10 tyre go on ok or do you put a different tyre on

My AF Rims fit fine on standard studs, had them a couple of years have they changed something?

Don't know I have the rear on but the front once the wave washer and split washer are on no thread for dome nut to grip

One scratched to f--k font Rim what a waste of money
