Tyres to fit something that isn't designed to have them!

Ive got my little ratted cruiser sitting waiting for some engine work to be done, since it has become a bit of a rat bike i plan to fully rat the thing.

For the tyres i was planning to but some heavy duty road legal off road tyes on.
But i cannot find any to fit the rims.

The tyre sizes are -
Front 110/90-16 and Rear 130/90-15.

Is it possible to fir larger rims to accomidate larger tyres, given that i am moving the front fender up and losing most of the rear bodywork.

 

I have a Fireblade 16" front wheel that will take a 130 tyre, but you would need discs, calipers and forks? I also have those items?

 

so from the sounds of it i would have to get an entire front end to put bigger rims on, im guessing that with the rear as lond as its drum brakes and i get rims and brakes together its just a case of making sure it fits in the swing arm?

 

The problem you'll find is that although motocross tyres are easily available in 15 and 16 inch, they're specifically designed for kids 'crossers so aren't road legal. TBH you wouldn't want to use them on the road anyway since they'd be greasier than a mechanic's fingers.

 

You can fit a wider rim to a wire wheel as long as you still retain the chain clearance and the brake rod clearance. It is expensive though!

 

As the guys have already said, wider / bigger wheels not from the same range / model is a fairly large PITA on bikes as there's stuff either side of said wheels.

If you want a rat look and aren't concerned about performance then look to the cheaper end of the market for tyres. Some of the brands make "extra super duper touring last forever" moulds that look dead chunky but also grip.
