Have '03 screw 4x4 stock hieght. Would like to go with LT285x16 Cepek
Mud Country or 305x16 on stock wheel, if not on stock wheel, then with
Pro Comp 7081/7089 16x8. Possible without lift?

 

Yes, you easily fit a 285/75-16 or 305/70-16 using stock or aftermarket wheels. Personally, I'd go with a 10 inch wide wheel for a more aggressive stance. If you use a 10 inch wide wheel you will have to trim a little plastic off the front bumper's lower valance.

 

Thanks W for your advise. Don't mind trim'n the
plastic a bit but I do a ton of highway drive'n
and was under the impression a 10" wide rim
would lead to quicker wheel bearing wearing.
Would love to see a set of 305x70x16's
stuff'n the wells---LT285's are same height
as 305's in Cepek mud country?
thanks again

 

Same height basically, the 285's are just 10mm narrower.

 

Thanks---but would the wider rim cause wheel bearings to wear faster,
due to heavy highway miles?

 

A wider wheel or tire will create more leverage leading to increased wear. How much? Who knows.
