Tire width with rear adjustable spring plates

[davisshannon]

I’ve got rear adjustable spring plates and wanted to see people’s opinions on tire widths?

The stock smoothies with 165/80’s have maybe just under 1 inch of space to the adjustment screw blocks on the spring plates.

I’ve got a set of the CIP Super Speeds (https://www2.cip1.com/c32-ss5205-5515-sb/) that I’m going to use. So the +14 offset should push the wheels out just a bit, but then they’re 1 inch wider than stock.

I’d like to get something wider than 165 in the back and stay close to stock circumference for gearing.

You will have heaps of clearance with wheels like that with very low offset.

185/70/15s are the same OD as a 165/80, but put more rubber on the ground. Perfect fit for a 5.5" wheel.

Thanks. I’ll see what I can find in that size.

A 185/65-15 would work as well- same width, only 3/4" shorter than a 185/70 (25.2" tall), a lot more choices and not nearly as expensive.

Thanks. Yeah, looks like I’ll be going 185/65r15’s as the 70’s aren’t that common.

I’m getting my transaxle rebuilt when my new engine is going in. It’s an Australian 1966 with a 1300 and I’m having a 1914/1915/1916 built (can never work out exactly which it will be). So I’m going to have taller ratios installed which should help with that slightly shorter tire.
