I'm looking to put Nitto ridge grapplers 38x13.50 R20 on the Vossen HF 6-4 20x9.5 wheels. They come stock +15 offset, my question is should I stay with the +15 offset to compensate for the extra 0.5" larger width from the stock wheel or go with the stock offset +19(Vossen offers custom offsets)? If I go with the stock offset (+19) it would put the wheel 0.25" further into the wheel well and 0.25" further out, splitting the difference (which seems like a good idea). I'm not sure if it would work without hitting the suspension on the inside or rubbing on the outside or neither but this seems to be the way to go? The +15-offset moving the wheel out just a bit to compensate for the wider wheel, putting 0.125" of the wheels further in and 0.375" further out. This seems like a good idea also providing it doesn't rub, I`m more Leary of going out with the wheel than in with a tire this tall.
Custom Performance thread on this forum put a Toyo Open Country M/T 37X13.50R20LT on his TRX and according to Toyo`s website this tire specs are 37.0"tall 14.0"wide and he had these results
Tires: 37x13.50r20 Toyo Open Country MT
Wheels: Fuel "Rebel" 20x9 with +20mm offset
Suspension Modifications: None
Trimming required: None
Rubbing: None
If I put a Foutz leveling kit on, 2021-2022 RAM TRX FRONT LEVELING KIT and 2021 - UP RAM TRX REAR SPRING SPACER LIFT KIT 3/4". I saw a guy on YouTube put this exact kit on his TRX and measuring from the bottom of the fender flare he had these results:
Front 39">42" Rear 42.5>44"
I should have no problems with a 38" tire. If Custom Performance can put a 37" tire on with no mods to his suspension, I should be able to put a 38" tire with a levering kit easily. After all we're talking 1/2" on the top and 1/2" on the bottom of the tire and conversely front and back of the tire, right? My question is what offset? What are your thoughts?
