Hey guys,does anyone know the factory offset for 20in ford f150 wheels?I'm looking to get 20in boss wheels(330 or 316) and there offset is +20 or +40,I want to see if these are going to stick out or be flush like the factory 20s

Thanks

 

I believe the stock 20s are either +35 or +42. I'm not positive what it is, but it is somewhere around there. The +40s would be almost identical to stock, and the +20s would stick out around 1" further than stock.

 

Thanks bro,is there anywhere I can double check I tried Google but I can't find any solid info on the stock offset.

this can let you play with tire size rim size, offset etc

 

I played with it before but...I does no good for a comparison on offsets if I don't have the actual F150 20in offset number

Thanks though

anyone else?

 

more then likely all OEM wheels are +42 or +44. which is roughly 6" backspace. it makes sense as i don't see why ford would change how much a wheel sticks out on a vast series of trucks with the same lug pattern/chassis

regardless, i used the model of +44 when rim shopping for mines, and it came out close to the real thing. what look are you going for? would you mind having the tire stick out a 1/4"? i like when the rims are flush to poking a bit, so if i were rim shopping i'd do the +20. do you have flares on your truck? that accounts for like 1/2" IIRC

 

The OEM 20's are 8.5 inches wide with 6.5 inches of backspacing.

 

bingo!
