Little bubba tire growth

After mounting these things up it looks like they may be too tall for my tubs. I lost two inches going from a 15 inch wheel and 16x33s to the 16 inch wheel and bubbas. Not sure if raising the rear of the car will do the trick if they grow higher than the Hoosier did. Thoughts?

I don’t think they grow a ton.. where they’re at is pretty close to where they’re at at end of track.. I’m pretty sure the 3183 and 319XW tires are same size at the finish line..

Radius or Diameter?

Daryl, how wide are your wheels. In general Little Bub's don't grow nearly as much as your typical 16x33 tire would. Mainly MPH and the car's weight determine how much tire growth you can expect.

1.5" total @ 150 mph

If it were my "wealth of knowledge" vs. everyone, we'd be racing. We're not racing, we're exchanging idea's on approach for racing.

If we were racing I'd still help you with approach and I'd race my street car Nova. Because it wouldn't be fair if I didn't.

My approach for this would be to raise the car 1" tops, maybe a hair less for, for ride height at speed (aerodynamics).

The Hoosier grows a hair more probably, but has a longer footprint front to back at speed. How much more who knows. Only trial and error

If it were me I wouldn't put much more thought in it after that, other than another dimension in wing height adjustment could develop anyway.

The wider the tread in comparison to the rim width, the more the tire grows and vice versa.

The other variable to take into consideration is the rear damper valving. My Ohlins TTX 36's can be adjusted to be digressive, shaft speed rises the rearend separates (jacked up).

There's numerous adjustments you can make to have the ride height at speed anywhere you find it performs best.
