Wheel rule for 05

[Marcus Miller]

We kind of already talked about it, but has anyone here decided on taking the plunge on 15 inch wheels?

Not me..
Negatives: No tires exist that won't hurt the gearing, extra weight, extra expense, and I don't need the extra room they would create anyway.

Advantages: More room for strut spacers.

I'm at 13X7, and 225/50/13 (Hoosiers), in an S car. I can fit 15s in the wheel well but have gear issues already anyway (too tall). Since I really can't go much wider, don't see much benefit to bigger wheels. But I'm new and don't fully understand the issue.

Disregard. Just realized this is the Mazda forum...GA

Looks like most of the 14/15" options are at least an Inch taller, so I can see your concerns...

They do have a 225-45-13 available (Hoosier) that is 1.1" shorter, however...

Currently I am on 225/50/13s, but plans have been made to do some back to back testing next spring with 225/45/13s.

I have resisted the change for reasons of gearing and shift points at Lime Rock, but I wonder if it's hurting me to not get the car down as absolutely low as possible.

So a testing we will go!

I went to the 225/45R13 in 2000 or 2001 (whenever they came out) and changed from a 4.88 to the 4.44. It's a different tire than the current one, but at the time that I made the change, I found the 45 series to settle down more quickly on turn in, and feel less spongy midcorner. I used this setup at Waterford Hills, and was very competitive.

Funny, Jake - I was going to try putting in my 4.88 in for my next weekend at Limerock, mostly to see if I can get better gearing for the uphill. I seem to lose the most time there, saying 'giddyup' to the car. If you are going for a practice day, let me know - maybe we can test together.
