If your current tire is a 4.80/4.00-8 size then your wheel rim width should be 3-3/4". You can verify this by measuring the wheel from bead seat to bead seat (see attached photo).

I recommend using the Kenda K353 Tire # AM10012 if this is the case. This tire measures 5." wide and has an 18" outer diameter when it is inflated to the 75 psi rating.
