i have a 77 f-250 crewcab 4x4 that im going to put 38 inch tires on 16.5 rims what rims do i need what offset and how wide do they have to be or will the stock wheels work? the tires i belive are 38x15x16.5 super swamper trl radial. and what are the stock size of a 16.5 rim (the off set and back spacing and width)?

 

I would go with 16s cause There have been lots of problems with 16.5s smaller beads and the tire can get poped off the bead alot easier than any other size. Just what I have heard.
for a 15 wide tire,I would go with atleast a 12 wide rim, or even 14.

 

Yeah...the 16.5 wheels are not good at all for holding beads. I would stick with a 16x12 wheel.

 

is this truck going to be a pavement pounder, or a mainly offroad truck? if its for the road, get a wider rim, as it will make the tires wear better, if you plan on mainly being offroad, get a skinnier rim, it will help hold the tire on the rim, but if you run a skinny rim on the road alot it will wear the middle of the tire more.

 

it's not so much the fact of a smaller bead, it's that the bead on a 16.5 is angled a about 45 degrees- where a 16" is straight up and down bead so the surface area is greater... if you run a 16" wheel and a 15" wide tire you can go as narrow as 8" or so.. the tire jockeys don't like you but you can air them dowm and they won't break a bead without some serious effort... i run 38.5x15 boggers on 16x8 wheels and haven't lost a bead yet- and hae been down to as low as 8 pounds in the tires...

 

well i got the tires cheap and my truck has 16.5 stock wheels and i was thinking that could i use my stock rims and if i get some extra cash i was going to buy new rims but thats a ways down the road. and searching the net i found out that for the tsl radial 38x15x16.5 the Tread Width is 11.50 in and the Recommended Rim Width 9.75 in. but will the stock rim width work

 

thelll work, just about any width will, its just how well

 

Do you have any pictures of these tires?I have been lookin at doing this but wasnt sure how it would look.A pic would be appreciated,thanks.

 

I have 38x13x16's on 16x6.5's They are on the 73, have photos.

 

they will work.....may rub on the leaf springs....and you will have to air them down a good bit to get proper wear if you driveit on the road. other than that they will work great for holding a "bead"

 

just got some pics... i'll be posting them in my gallery later tonight...
