Hi ,i have an 68 buick skylark 4 door custom hard top ,just got painted,i have 14" rim on now,i would like the upgrade to 15" what whidth would you recomended in the back and front and tire size thanks , Denis
I would use 15 X 8" in the back. The 68-69 need about 5" back spacing on the 8" wide rim. You can run up to P275/60-15 in the back. Front can be a 15 X 7" wheel with 1/2" backspace. P25/60R-15 is a nice size for the front, or all around if you prefer.
If you flip a rim around and lay the outside of it on the ground, back spacing is the distance from the bead mounting surface to the lug mounting surface. If you order new rims, you need to specify the back spacing.
Thanks for the help,if you go to color is everything forum you will see an picture of my car,i know the back fender there is not much room for wide rim will this 15x8 whit 5 back spacing fit just hopping ,thanks again
I have a 70, and I use a 15 X 8 with 4 1/2" back spacing. I am pretty sure the 68-69 needs a bit more on an 8" wide rim. You may want to wait for the 68-69 guys to respond to this thread, to be sure. I believe 5" is what you need. With the right back spacing, yes, the 15 X 8 will fit.
Is there anybody out there have an 68 skylark ,just want to make sure before i order my rim thanks guy's, would it be better if i go with 16" or 17" insthead of 15"
I have 16x8 that have a 4.5" back spacing on them and had to trim a bit off of the wheel well lip to get them to fit. I prefer to run the same size tires/rims front and back for rotation purposes and mine is a daily driver. I believe my tires are 225 65 16's. My suspension is all new also and the tires don't rub.
And that fits with my post that says the 68-69 need a bit more back spacing. 5" back spacing on an 8" wide wheel should do it.
1969 - 15" 275x60x15, 5.25 backspacing... rear lip is trimmed. Probably could still go a little wider. James
I forgot to add, but mine had skirts originally which has a tab and bracket that stick out and that's what needed to be trimmed. I took a wheel well trim piece and I believe I could have trimmed it back another .5" - 1" to the inboard edge of the installed trim for more clearance.
Now that i have a couple of option what would you recomended overhall,front and back whit tire size please ,something i can put on whit no trim to doo thanks for the help guy's .If i decided to put disc brake kit would this affect anything .
