I want to move on up to 36's or 37's and regear but 1 problem.... I run stock tires in the winter (because of salt) and am wondering if while i have the stock tires on if I will have an issue of going down the expressway at like 5 grand because its not pulling that "extra weight" (the tires) BTW thinking 4.88 since I pull things quite often but also thinking 4.56 tell me what you think

 

Do 456 even with 36s won't be bad.

I run 33 with 456 in summer and 32 in winter on my stock 5.4. It doesn't buzz that high on highway. Also could use 285 75 16 for winter tire to put you at 33 for winter. Thats my plan next year.
