325 Tire?

[danno1]

Someone on YouTube installed a 325 wide rear tire on a 2019 PP 2 wheel. Would that work?

I had 325s on a set of SVE SP2 wheels and I didn't like how much they poked. They never rubbed however.

The YouTube said it now matches the width outside the fender as the front PP2 wheel

I run 325/30/19 MT drag radials on my ‘18 PP2 without any issues. They are mounted on SVE SP2 19x11 +50.

So I guess it's possible on the pp2 with the offset?

They would be fine on the stock PP2 wheels as well which are 19x11 +48.

How much wider is a 325 over a 305?

How much wider is a 325 over a 305?

10mm on the inside, 10mm on the outside. 10mm is about 0.4”. Also realize not all 325’s will measure identical. With the 19x11 +50, the 325’s stick out about 1/3” farther than the stock 305’s on the 19x11 +48.

Also realize a 325/30/19 is about 1/2” taller than a 305/30/19, so it will also effect your gearing a little bit. The 3.73’s with the 305/30/19 are about like a 3.93/4 rear gear when compared to the 275/40/19 on a PP1 with 3.73. I can trap about 114-115 in the 1/4 mile in 3rd gear with the 325/30/19’s.

Would never expect that tire being taller half inch. So, if that same tire were a 325/35/19 would that be same height?

No.

The '30' and '35' are not hard sidewall height numbers. They are sidewall heights as a percentage of tire section width.

To the nearest 0.1"

305/30-19 is about 26.2" tall, each sidewall would be 305 x 0.30 ÷ 25.4 = 3.6"
325/30-19 is about 26.7" tall, each sidewall would be 325 x 0.30 ÷ 25.4 = 3.8"
325/35-19 is almost 28" tall, each sidewall would be 325 x 0.35 ÷ 25.4 = 4.5"

A proper wheel fitment for a 325 is more like an 11.5-12" wide wheel. The "will it fit" ? Sure, you can mount a 325 on an 11", and for a drag tire, it may not be a huge deal, but you're introducing a bit of a compromise in overall handling (and may not even be increasing the contact patch that much).

FWIW, I run a 305/35 on my rear 20x11 wheels (ET50 offset).

Got it. Thanks guys. Very interesting.

I run a 325/30R19 on a 19x10 wheel. Saves on curb rash. Clears everything. Fender gap sucks.. but I ain't lowering it.

Would you have any pics on different angles?
