Setting a new wheel tire package for my O4 vert and I could use some assistance.
Problem Statement:
- I'm having a difficult time deciding on sidewall height.
Option 1: 315/30/18
- this option will bring me slightly shorter in total tire height than stock. Stock = 25.7 in (total tire height) VS ~25.4
Option 2: 315/35/18
- this option will bring me ~1 in taller than stock. Stock = 25.7 VS 26.7
Background Details and Assumptions:
- Convertible
- Currently on factory wheels and tires
- New rear wheels will be 18x10.5. Offset = 22
- Rear tires will be R888R's
- The car will be lowered. However, I have not determined what springs I will put on it. I plan to retain my factory struts/shocks. Perhaps down the road I may go coilovers, but I'll cross that bridge later.
- Expect I will need to shave or replace my IRS bolts
- Car use - Street car, weekend cruiser. I do drive it hard very hard and like a stiff and compliant drive.
- Fenders are factory un-rolled.
Open Questions:
1) with the 315's, I presume I will need to roll the fender. I was considering using the Eastwood Fender Roller. Any recommendations pro or against this approach?
2) I am torn between the 30 and 35 sidewall tires. Any recommendations on commonly used tires? I am seeing both from the posts that I read.
3) I haven't determined my lowering approach as of yet. Any recommendations in this area are greatly appreciated. I realize this has a contributing factor towards tire selection and avoiding rubbing. I like a low, stiff, yet streetable car.
4) With lowering considerations in mind, should I plan to purchase anything else to correct my geometry? E.g., Camber/Caster plates, etc.
5) with my offset of 22. Will I need spacers for clearance? If so suggestions on size to avoid rubbing with 315's?
Guidance, and pictures of your setup are greatly appreciated!
Thanks in advance!
