How should I select tolerance and dimension for rim and tyre?

Hello everybody,

I designed a tire (plastics) and tyre (robber, solid) in the NX11. I should do drafting and should do dimension and tolerance for it. It is a little hard. Can anyone help with this. please send me massage if you can do it?

Thanks
Sara

Hard to say, undoubtedly an 'interference' fit but without knowing the application, it's a crap shoot.

Here is picture of my wheel. Rim+Tire

The tyre plus sizing or the tyre upsizing is the procedure of replacing a wheel with a larger one and mounting a lower profile tyre while keeping an overall tyre diameter and a tyre circumference the same or approximately the same as it is for the original equipment(OE) tyre.
The most popular Plus Sizing methods are:

Plus Zero - utilizes the same wheel diameter as the OE tyre but combines it with a tyre which has a larger section width and a smaller aspect ratio than the OE tyre.
Plus One - utilizes a one-inch larger diameter wheel in comination with the tyre which has a one-step lower aspect ratio than the OE tyre.
Plus Two - utilizes a two-inch larger diameter wheel in combination with the tyre which has a two-step lower aspect ratio than the OE tyre.
Beware that the Plus Zero method may require a replacement wheel in order to maintain the proper rim width for a new tyre. Methods: Plus One and Plus Two always require a replacement wheel.
