As far as tire diameter is concerned, there are no restrictions, assuming that the tire fits into whatever the fenderwell modificatioons, if any, are allowed. This is very important because a larger diameter tire will have a longer footprint, everything else being equal. On the other hand, a larger tire diameter will effect overall gearing so this has to be considered when choosing a rear tire size. Actually, the smaller the overall footprint on the pavement, the more pounds per square inch of footprint is available. And there will be less rolling resistance, also.
Some racers have the wrond rim width for the tire.
All drag tire manufacturers list recommended rim widths for the different tire widths. If the rim is too narrow, the sidewalls will be pulled inward and buldge the middle of the tread out. Since air pressure plays an important part in total footprint, it is probably advisable to have the rim width and tread width close to the same width. Let's talk about air pressure. A good tire gauge is the chassis tuner's best tool.
