235/40/17, a dying tire size?

The affect on gearing of the taller 245/40 would actually be beneficial for me since I have a 4.10 rear end now as opposed to the 3.73. And our region builds long, quick courses.

but they'd rub like a mofo

Street tires only Lee, this for Street Tire Auto-X, basically I'll be running Street Mod Street Tire class because of the diff, otherwise I'd be running DSP ST.

235.40.17 is still available from Toyo R888 as it was from the RA1 line-up. Sure it is a track tire, but such a wide tire wouldn't be require for street use.
For street, then a 225 is more than adequate.

245.40.17 is more an e36-e46 size. Way too tall, and too wide for an e30, unless it is an e30 M3 with even wider flares.

I've noticed since the summer there are less and less tires in this size. However, 245/40 seems to be growing.

Makes me wonder if I should go ahead and get my fitment setup to run 245/40s. Or am I being paranoid?
