oil presser

if i rase my back end 2 1/2 inches with taller tires,on my 1948 1/2 ton.Would that affect oil presser on my second series 235 engine ? thank

 

No it would not. If you drive down a hill you don't worry about oil pressure.

 

That's a BIG change in tire size. What size are the tires, old and new?

 

tires up front 215/70/15 tires in back 235/75/15 on original 4 by 15 rims ,is that ok?

 

4 inch wheels are pretty skinny for a 235 tire.

Check out how recommended tire sizes / wheel widths are figured at this link.

 

tall tires

So, youre going to buy tires that are 5" taller than what youre running now?
That's quite a jump. Probably quite a jump in price also.

 

That 5" was exactly my point, but I wanted to see if old chevy guy caught it. More likely the new tires are 2.5" taller which would raise the rear 1.25"

 

i think it will only rase it 2 1/2 inches .Some one told me the narrow 4 rims will not matter on non steering tires, the guy who wants to sell me the tires.thanks
