Barracuda's with 335/30 on them?

13.5 section width for the 335. Will the tire be narrowed at all by the rim?

Maybe. I notice there are some discrepancies in section width depending on the manufacturer. A narrower wheel will narrow the section width some but not much with that particular tire.

I run an advertised 13.1 section width tire under my car. Since I run it on a wheel that is the max recommended for that tire it actually measures a little wider. They fit but its close. you may need to do a little massaging if the lip. the height of 25.90 shouldn't be an issue.

I think they will fit. especially given the tire profile and the chassis setup you'll have for running that tire.
