Tires and Mini Tub

[mdprovee]

I am going to be mini tubbing my 67 camaro, and adding disk brakes. I will need to get new rear wheels and tires also, because the stock wheels I have now will not fit over the brakes. +



So I was wanting to go with a 18" wheel, with a 315 size tire. Looking at some tire websites for sizes, it looks like a limited selection. So my question is, those of you that have mini tubbed the rear, what kind of rear tire and what sizes are you guys running. Will I get a better selection if I go with 17 wheels? Do I just need to step up and go with a 335 size tire?

What width wheel are you running, I was thinking of using a 10 or 11" width wheel. I was looking into some Budnik wheels, but it appears that the 18" wheels only go to 9 1/2" widths. Can different widths be ordered? Thanks in adavance.

I went with 18x12's and a 335/30. Bundnik will build you a 12" rim, but the only drawback is it will cost you almost double. I guess it all boils down to the look you want to acheive and the money you are willing to spend.

I'm going with Kinesis 18x12s w/ Michelin Pilot Sports --335/30/18s.

315 will work best with an 11 rear rim. thats what im goin with on my 68, 19x11.

I am going with a 315/35/17. I am going with those to help keep the width difference between the front and rear to a min. You would need a 12" rim for the 335's.

Jonny it is unfair to show those rims because they are a blob of metal and rubber now.

Jonny, what is the backspacing on those? I'm looking at some Weld 18x12's right now and am trying to guesstimate the backspacing I need until I can get home from Iraq and do some measurements.

Brian the car is being resurected well its a whole new car and well you will see!

Those wheels were 18x12 -13mm offset, 5.875 Backspacing, caliper clearance 1.625

Oh and thanks for defending are county!!

[baz67]

patrolman, keep in mind that the backspacing is dependant on the over axlenflange to flange width. When you know that you can determain the correct backspace for your car.

Jonny I know, but still had to jab a little.

I was just about to ask this question myself. I am doing a '68 Camaro and I have been really weighing the pros & cons of mini-tubbing or not and if so what size is right for me.

Here's my dilemma.... I really don't want to have the biggest tire just for looks... I want big tires to make a big difference if I'm gonna spend big $$ for them. A close friend of mine works for Kumho's Motorsports support/R&D and he told me that the race teams don't really like to even venture into wheels bigger than 17".

He also reminded me that if I stayed with wheels and tires from say a Z06 I would probably be able get replacements just about anywhere in the US. To me that just makes common sense....


I just think that have a big tire for looks is not enough..... don't get me wrong it LOOKS WICKED, but they don't necessarily perform that much better if at all than say a Z06 295/35/18 rear.
