1984 xtra cab toyota p/u tires
 

My truck has large tires on it and I want to go to a smaller tire but Walmart does not have the specs on tires allowed by the toy manufacturer. So, they can not sell me tires without a list of allowed tires for that year and model. Does this make any sense? My question is, if they dont have the liist of tires allowed how am I supposed to get it? It is odd that they have nothing on a 1984 xtra cab unless that is not how it is listed. Does anyone know another model name that it might be listed under.? or how I might get a list of tires allowed for this truck.
Thank you :nopity:

1984 Toyota Pickup, regardless of the cab

Hope this helps!
