another fantastic conversion table can be found on:

Unless someone can prove me wrong, nothing beats Mark Sink's calculator.

This is the first time I've looked at it in a while, and it's better than ever.

Are all 16" rims able to fit any of the first numbers? According to that table, If I was to go with a tire that is 185-45-r16 or 195-40-r16 or 205-40-r16 I'd be ok. The rims I have right now have 205-45-r16 on them, and I need to know if any of those sizes will still fit the rim.

these are the rims I have:

If you're talking about the link I sent, it doesn't account for rim width. It's really best to use if you're starting with your stock size tires and want to know what fits and keeps you within a specific speedometer error range (in other words, staying as close to stock diameter as possible).

What car do you have, and what's the stock size tire?

I have a NX, stock 14" tires. The rims I've got are riaxx seca 16" tires. They have a 7" width according to the website.

chriscar

NX's came with 195/55/14's stock. So plug that into the calculator, set the max size to 16" 225mm and 2mph error, and you'll get a bunch of results. Not all of the results are actual sizes that are made though.

A 205/40/16 is the closest match in overall diameter, and there are allot of tires available in that size. You don't want a 185 or 195, it's just too narrow for a 16", and there are only a few made.

As far as what will fit on a 7" rim, a 205 will be fine.

sweet. thanks again chris, you once again prove yourself to be the best at this stuff.

the offset on the nx is 40, this rim says +42mm, do i need a spacer at all then?

chriscar

Hehe, don't ask me. Offset confuses the hell out of me.

i'm thinking it's just a typo, but the B14 SE-R came with 15" stock wheels.

whoops! my bad, edited.

Canx2k

anyone?

spnx

Lower the number = wider the track, because it's positive offset. With a 7" wide wheel, I've found a +35 offset to be perfect for the NX2000.

Ok, so I guess going from 40 to a 42 isn't a big deal from what i've been reading. But I'm a little wary on going to 16" rims which are 1" thicker, bolting them up and getting rubbing. I have stock shocks, so would I need a spacer, or anything of that sort to prevent rubbing?

No way, Sink's is way better.

Coolness. When I did my tire fitting I just dialed in Google and looked at what popped up (1010, Tirerack, miata). I like the Sink page, Chris. Thanx.
