hey guys, i'm buying new wheels and tires today, and need a quick answer... i've done some searching but just keep coming up with different opinions i just need a direct answer of will it fit, and will it look good
the whole wheel and tire package is costing just over 800 so i'm not expecting show-worthy appearance, i just need to know if its going to look good.

the wheels are 17x7 +38 front and 17x9 +35 rear

and the tires are 215/45 fronts and 225/40 rear...

please let me know what you guys think

 

I would get wider tires.

I have 215 on stock tires, then some 16x8(.5?) with 245's But I like wide tires on rims.



Really, it's about opinion though. Sorry that doesn't help much.

 

I would get tires with the same aspect ratio, unless you want to run a taller tire in the back...

 

ok, so im thinking im going for 215/40 in front and 235/40 in rear, i want a low profile look... i don't track the car just spirited daily driving right now...

 

If you care about whether or not your speedometer will be accurate, you want to buy new tires that have as close to the same overall diameter as your stock tires did.

I see you have a '91. If it's an NA, it came with 205/60-15 stock. If you want 215s up front on a 17" wheel, the closest overall diameter to stock would actually be a 215/45-17. For the rears, if you want a 235 section width on a 17" wheel, you'd want 235/40-17.

Remember that aspect ratio is a percentage of the section width of the tire, which is why a 215/45-17 is almost the same height as a 235/40-17.

You might want to play around with the Tire Size Calculator from Miata.net. That does all the math for you in terms of overall diameter and comparing what you're looking at with stock:
