Wheel width for 315mm squared?

Trying to make a decision/compromise based on a hypothetical situation that may happen in the future is difficult. Side story, somewhat related. Every manufacturer makes an "all season" tire. They work in all seasons, just like it says. But they don't work the best in any season so I call them no seasons.

Point taken. I would say these aren't hypotheticals, though. Purpose isn't a question for me. I know what the usage of the car will be when all is said and done. I do understand what you're saying though and it does make sense. I appreciate the perspective.

Picking a wheel width that will work with 315s and 285s is easy. Buy the 11s, they will work with both tires but they won't be the best for either. You spent a lot of money on go fast parts and it seems that go fast is what it is all about. Buy the wheels that optimize the go fast and deal with the street side later. There are several ways to do that. A set of Forgestars would run $1,500 or less, you could run 10s all around with 275-295 or whatever.......but long before I did that, I would see how many "street" miles the car actually sees and if there is even a problem running the "race" rubber all the time and deal with it then.

Go fast is part of the equation, but it isn't the whole equation. If you check out the link in my signature, you can get some insight into how I'm planning this project.

That being said, I haven't compromised in many places so far and I don't know why I'd compromise as much as everyone is making this seem right now. I spoke with Forgeline this morning to see if it was possible to order just an inner barrel so I could effectively make the 18x11.5 I'm initially buying into something like a 18x10 for daily driving. They said no problem, that people do it all the time, and that I'll want to use their gasket seals instead for quicker changes. So that's an option right there. Run the 315 on an 18x11.5 (or hell, 18x12 now), then change out the inner barrel so they're 18x10 and run a more streetable tire. So this isn't the no compromise solution of just getting two sets of wheels, but it's not far off either and it's saving me $5500 in parts.

Thoughts on this?

Something to consider... Ill assume weather is not of concern. Most of us arent driving in the rain (intentionally) or snowy weather (waiting for AndrewB to reply to this ). So the only concern is tread wear. Is the wear from street miles worth the additional set of tires, barrels and time to swap out? I also like getting seat time with the car as it would be on the track, while I drive on the street. Makes familiarizing yourself with the car far easier.
As you can tell, Im in the group of "just run your track setup on the street" Ive got 18x13's and stretched Toyo R888R's that will probably get more street miles than track time.

Yeah, weather isn’t a concern here in California. My only concern is daily driving tread wear, cost associated with it, and safety. I’ve budgeted my tread wear cost for track days already, so I’m only dealing with the daily driving aspect of it.

You bring up very legitimate points. I’ll need to do a proper cost analysis to see how much these options are. I am someone who will pay for convenience and, if I were to guess, I’m probably going to get pretty tired of the man-hours needed to maintain the countermeasure of multiple inner barrels and converting of the wheels, particularly if I’m doing the conversion 20-24 times a year.

Writing that out helps put it into perspective for me. I might very well discover NOT running a my track configuration on the street is cost prohibitive. If that’s the case, then safety might be my only concern.

I gave you a cost analysis before. $277 for the 200TW Falken tires is much cheaper than the other 315 tires and they fit 11.5” recommended wheel mounting width.
