Rim sizes for DC2

[Moya]

I'm upgrading my stockies on my DC2, just wanna know, with the size of the wheel arches etc etc, what is the optimal size for the rims and profiles?

At the moment there R15/225's I THINK - If I went to 17's and slightly wider with a low profile, what numbers should I be looking at? I asked tempe, and they said they weight in at approx 6KG each, so I dont think weight will be a problem.

In other words, I'm buying these (http://www.tempetyres.com.au/products_closeup.asp?part=&part_no=481) rims start of next week, what R17/y/x should I ask for?

I don't want to lose acceleration, and
I dont want to have my speedo recalibrated.

Thanks

Hey Moya,
Those are awesome looking rims! I don't think your rims are R15 225's though. That seems a bit too wide. With 17 inch rims, the tyres you are looking at are 215/35/17R. These are the closest size to keep your stock rolling diameter so your speedo will be as accurate as possible. With 17" rims and a good quality low profile tyre, you will gain acceleration, braking and handling!

Have a look at the 15''s on your car at the moment and get the tyre specs and plug them into this web site to see how far off your speedo will be with 215/35/17 tyres. Tyre Size Calculator (http://www.miata.net/garage/tirecalc.html)

You could probably even get away with 215/40/17, thats what i have at the moment. Those rims will fit your DC2 nicely, so when you get them, take them to your tyre place and they will help you with the best possible tyres for how you want your car to perform. They also have a listing of all cars and tyre sizes.

Thanks south, very helpful!

Will 215 be too wide? I've read alot of threads on here, and the consenses seems to be 205/40/R17 to be the best, because a few people on 45 seem to be scraping?

That link is great, on 40's i'll be 1.4% too slow, at 35 I'll be 2.2% too fast. Stock tyre for 95 Teg VTi-R is 195/55/R15. Both, basically irrelavent. I might go the 35's as it'll be thinner.

Now all I need to worry about is the wideness. Will 215 definately be okay? What does the 17x7 rim convert into in regards to 195/205/215/225's etc?

Once again, thanks.

I've been running 215/40/17's for a month now and havent had a problem with the tyres hitting or rubbing anything when i turn, so i don't see it as a problem. However over the next couple of months i will be adding a full kit and lowering my teg, so i am a bit worried that something might hit when its lowered, but thats why god made adjustable coilovers!

Bottom line, on a stock teg, 215's give enough room for the tyre to move comfortably without hitting anything. And 215s are wider than 205s so more tyre surface area means more traction, and that will help with steering and acceleration, therefore i sleep better at night knowing i have 215s.

My rims are G.Max M111 (http://www.spinnerwheels.com.au/88a13ed0.jpg) in white and they are 17x7 with 215/40/17 and they fit perfectly. So you shouldnt have a problem fitting 215/35/17 on your rims.

Hey Moya, I also have 17x7 215/40/17..
they scrub a little bit when I corner hard, or when I have a car full of passengers, but over-all, when im doing daily driving they are really great.

Anything larger and it's really not worth it, I find that the ride isn't too bumpy, but I dont like to go too fast over the crappy burwood highway in vermont south

Is the scrubbing due to the 40 or 215 though?

If I dropped to 215/35 would that fix it?

copycat:P
gold wheels are the shizzzzle

also how low your car is will depend on the rubbing.
i have 215's/40/17's and they only rub when i have more then 1 passenger.
i suggest this size and it is the biggest you can get that is still practicle.

I have 225/35/R18 on my DC4 and there's some scrubbing at the front under full lock. If I take a corner sharp and fast enough, there's also some scrubbing at the rear. My car is 'sports low' on Kings springs.

I did have 215/45/R17 on there previously, and I can say that the new rims/tyres give a much better ride quality, and handling.

srubbing = gay.
i cant imagine them handling better.
for performance i would go a nice fat set of 16's..
18's and handling is very very hard on a small car.
i dont think i'll take your word on that one kenno :confused:
although what would i know... ;)

probably a bit of both, cuz it only scrubs just on the edge of the arches, nothing that a rolled guard wouldn't fix...

plus my car is at stock ride height at the moment...

Are 17's on the DC2 illegal? I'm looking to do what Moya is (new rims, 17's on lows) but I'm curious about the legalities for QLD. If I recall, I believe your allowed to increase rim size by +2" - so this is fine as stock shes 15?

yeah mate its legal.
i have been through a few defect stations and nothing been said about the wheels.
i think as long as the rolling size is still the same (diameter) its all good news... :)

Thanks buddy, my concern being in brisbane ISNT police, but same as Moya, having insurance void due to be illegal :thumbdwn:

In QLD, you must keep the rolling diameter within +/- 26mm from stock. For example, the stock rims/tyres for my Integra were 14inch rims with 195/60/R14 tyres. The rims/tyres on now are 18inch rims with 225/35/R18 tyres. The original rolling diameter was 590mm, the rolling diameter of the new rims/tyres is 615mm. So I just barely scrape in the legal limit by 1mm.

Forget this 2inches BS, that's the old ruling. Don't forget load rating either, you'd be a fool to drive around with tyres that don't meet it! IT'S UNSAFE, defects, and bye-bye insurance if you crash.
