Will 255/45-18 wheels rub on dna drop springs? Wheel experts need advice!

255/45 is going to be a hair wider. But, as far as preventing bent rims, its only 2/10 of an inch taller than a 245/45, so it really is not much more cushion.

^ he's right.

run less air pressure in your tires. save wheels at the expense of a little less MPG.

Yup. It is also a comfort issue. According to the miata tire calculator I would be going from a 3.9in sidewall to a 4.5in sidewall.

My current tire size is 245/40-18 reason I got that size was because the tires were almost new and got them for a steal. But tired of the rough ride and want more meat on my wheels.

So the overall consensus is that i should be fine running 255/45-18 tire size on my 1 inch drop DNA springs?

Yea, what's the offset of your wheels though? That might come into play if its low enough. Although you're already running 245s I'd say you'll be fine.

245/45 puts you at the stock height anyways.

Will be fine. But I doubt the drop will be that much with those springs with the pics I have seen.

I put 255/45/18 on my new Enkei's and New KYB quick struts ... And have rub! It's not the fender, the tire actually hits the spring perch on the bottom of the strut. Only when I have weight in the rear. I think I have pics, I will post if I do.

that doesnt move so if it doesnt rub just sitting there then it should never rub.

I'm assuming it sits so close that with a loaded car the tire bulges towards the perch some and rubs. Tire shouldn't bulge a considerable amount I wouldn't think tho so maybe your not running enough pressure?

My thinking is to eliminate it by throwing in coilovers in the rear for now, lol. I know the lower strut doesn't move but on right hand turns with weight oin the rear it rubs. There's no markings anywhere else (wheelwell) so... Obviously 245's would've been the right move. Drunkie suggested I sell them, might still as they got barely 5k on em... Great rubber too. I just don't want to go through the trouble of mounting new tires... Lazy I know. The spacers are an idea I haven't considered, interesting :) and a possible cure!
 
Re: Will 255/45-18 wheels rub on dna drop springs?

Coilovers would be worse if you're already rubbing. The spring goes over the strut so there's now less clearance.

thats what i ran with a 42mm offset and didnt rub at all
