There are two reasons.

The car feels numb with the 18" setup, which makes it a little less fun to drive. The numbness is most likely coming from an increase in weight by 15-20lbs per rim/tire combo, over the 15's.

my 15" rims: 16lbs
my 18" rims: 26lbs

That's before the weight difference in the tires. I also think the gearing change adds to the numb feeling.

Obviously numb isn't necessarily slow.

The second reason is the cost. I know it's only a $300 difference, but I have a mental barrier of spending over $1200 for a set of tires that will get less than 100 miles of use. That puts an autocross costing me close to $150/event. Not counting gas.

Good common sense man. What are those 18s made out of, lead?

Given the choice between "slow and feels great" and "fast but feels a little numb," I'll take fast but numb. Every time.

I think the 275/15's would give me 98% of what the 285/18's do, and presume that they would bring back the "feels great" feeling. Unfortunately, I don't know that they will accomplish that on 15x8 rims. And in order to get lightweight 15x9 or 15x10 rims, I'm in for another set of $1000 rims, that I really just don't want to spend on rims right now.

If I were certain that I was going to stick with autocrossing and not continue my recent occurance of bailing on events, than it would be a no-brainer.

buy the tires that would be an incentive not to bail on any events!

We ran the 225 15s on 6.5 rims, the 275's ought to work on 8" rims.
How do the diameters match up?
