18" wheel/tire combo sizing - The 1947 - Present Chevrolet & GMC Truck Message Board Network

67Fleet · 08-15-2005, 09:50 AM

Hey guys, I recently sold my 20" wheels/tires from my '03 to get some scratch together to buy some rollers for the '67. I want to get some 18's for it so I still have a little meat on the sidewalls. What backspacing should I get for the wheels to tuck? Also what size tire do you recommend? Heck, I may even be open to do a 18/20 combo. Probably 8" wide front and rear if I stay with 18's, and 8" front, 10" rear if I got 18/20. Thanks!

Up front, 18x8's w/245-45 or 235/50 using 5" back spacing. Out back, 18x10's w/295/45-18's or 20x10's 295/40-20's using 5" back spacing.

here's a question ... not meaning to hijack your thread 67fleet, but I have four 18" x 8.5" Billet Specialties Pomona's that I picked for a steal. I would like a little side wall in the rear too ... what would you guys recommend for this wheel combination?

I was thinking about 245 - 45's on the front ... but unsure of the rear.

Any suggestions? Thanks!

no prob Shane. Hey, what's the backspacing on those Pomonas? That size is exactly what I'd be looking for. Wanna sell 'em???

i run 255/55/18 on my truck all around with a 2" drop. i plan to run these sames tires (hopefully) when i do a 4/6 drop. and i agree with the backspacings stated above.

Backspacing is 4.5" if I remember correctly.

They are brand new ... never had tires mounted on them. Yeah ... I will sell them.

PM me ... we can talk.

Billet Specialties GTX 40 - was known as the "Pomona" when the GTX line was called the Premier line. The matching steering wheel is still known as the Pomona.
