Recently upgraded from a 79 Vanguard class c to a 94 27 foot Winnebago Brave. There is are several makes of tires on it, all in fair shape, but i have some new ones available which I would like to install. My question concerns tire size, the current tire size is LT 215 85 R16. The new ones are LT 235 85 R16. The are slightly larger. Does anyone have thoughts about this? There looks to be enough clearance. I also need this unit to pull a large horse trailer. I can't find any GVCW rating on this unit, tongue weights and such. Would anyone have experience with pulling large loads with this model of motorhome? The previous owner pulled a hot rod on a trailer to car shows. I am hoping this rig has enough jam for the job.
