Tire & Wheel Questions

[Kiquee71]

The car is a 1971 Nova and have some tire and wheel questions for you tire guys and would like your input. Ok the tire is a 335/30RZ18 Pirelli Rosso, it measures side wall to side wall 14-1/8" without the wheel mounted. Stuck it under the car and have under 1/4" on each side of the side walls. My question is when the wheel is mounted to the tire does it suck in the side walls a little bit? Does anyone have a true side wall measurement with 335/30RZ18 from other brands such as BFG KDW2, Rival & 18x12 wheel mounted together? This measurement would help with my decision to stay with this tire or go down to a 315/30RZ18. Any info would be great.

Not the same tire, so there could be some variance, but this might get you in the ballpark. 18x12 w 335s... came to 13 1/16th for me. I'm trying to load the pic for you with the tape measure pulled, but Firefox is acting slow. Someone else may be able to 2nd this.

EDIT: Forgot to mention, it is a BFG KDW, measurement is from outer faces of the sidewall project up, not the tire patch, so it would be more indicative of the total width you would be looking for (space and rub considerations).

Thanks Chadman27, that's what I'm looking for cause this Pirelli I bought to mock up is very wide compared to it spec sheet. Thats why I want guys with BFG's to chime in with their measurements so I have a good idea of what to run with. If the BFG are indeed a little narrower this will work and give me more like 3/8 or more room per side of the side walls. Come on guys chime in a give me what you got on your bad ass rides. LoL thanks

Ok, I've gotten a few responses from members with measurements regarding the various 335/30/18 sizes out there. Have to say thanks to all that responded because I've decide to stay with the 335's after all and when work slows down going to finish up mini tubes and start ordering my wheels and tires. Want to share with everyone what I found out so they don't go through what I've been going through wondering if or not are they going to fit. Have four brands so you guys make your decision in what to run.

1) BFG TA KDW 335/30/18 with
18x12 wheel mounted side wall
to side wall comes in at = 13 1/8
+-
2) BFG RIVALS 335/30/18
w/18x12 wheel side wall to
side wall comes in at = 13 1/8 +-

* these two above now are on back order and hard to come by now a days :( which bites

3) Michelin Pilot Sport
335/30/18 without
wheel side wall to side wall comes
in at = 13 1/8 +-
* this tire is available but is on the pricey side and have many sizes available like 265mm, 275mm for the fronts.

4) Pirelli P Zero Rosso
335/30/18 without wheel side
side wall to side wall comes in
at = 14 1/8 +-
* really WIDE tire for those who can fit it

Anyways hope this helps others cause it really helped me out. Until then.
