15x8.5" Torq Thrust on 1970 Chevelle
 

Folks,

Has anyone tried to run the vintage 8.5" TTs (3.75" backspacing) on the back of a '70-72 Chevelle? How is the fit?

15x8.5 with L60
 

Here you go

Awesome! Can you tell me the tire size?

I believe they’re L60-15 tires

Exactly where I was going with mine. Thanks guys.

They are l60 Pro Tracs,they will definilty not fit inside the fenders,I changed rear coils to lift it several inches

Thanks - do you get any rubbing on the wheel lips?

No rubbing,but it does sit a bit high

Same here, but I like the rake lol

If you get something with a little more backspacing, you won't have any rubbing issues. I have 15 x 10 Centerlines on back of the 68 El Camino, and the outer sidewall doesn't even come close to rubbing even with 275 60 15 tires. I am guessing you already knew that; and were just wondering about 8.5 width with only 3.75 inches of BS.

Unfortunately, there are not many options for backspacing with the new TT wheels.

There are options, they just cost 3 times the money. The price is appealing but the cheaper ones are only 3.75" back space as you mentioned.

Doesn't work on a chevelle if you want to put some tire under it. I run the torque thrusts on mine with 4.25" back space with a 275-60 tire and it fits under the car no problem with the back end sitting down.

Do you have a link to the wheels you’re talking about?

I've bought a couple of sets from "wheelsforless"

They don't list the other offsets on their site, I assume because the price scares off customers. But if you contact them, they do sell other offsets. At least that's how it was a couple years ago unless something has changed. Hope that helps.

Just went back and looked at my receipts. To give you an idea, the last set I bought, which also only showed 3.75" offset was $96 a piece from Wheelsforless. They are the classic Torque thrust just as pictured above. They offered to move the offset and the price was $310 a piece.

So more offset is offered (was last time I purchased) but the prices and offsets aren't listed on their site, have to call.

I’m guessing you have the custom order TTII wheels which are a 2-piece design with forged barrel. They don’t seem to offer them in 8.5” wide, but do offer them in 9”. They are considerably more @ 469/each.

Here is what AR offers for cast TT-D “off the shelf” wheels:

And here are the “custom” TTII sizes:

Vintage Wheel Works has V45 (d spoke) and V40 (straight spoke) cast 1 piece styles in 15x8 with 3-7/8" OR 4-1/2" backspacing for less than $200 per. http://www.vintagewheelworks.com/products/wheels/v45

Exactly...I have had this pair of early 1970s straight-spoke TTs for years and want to finally put them on something. Wish the BS was deeper but what can you do.

Here's my old Chevelle .I had 15x8.5 with 28x10.5 Mickey Thompson sportman pros but it rubbed.I reordered some 15x7 and the fit under the wheelwells.

Here's another pic with the 15x7.
