280z money pit Posted May 12, 2010 Share #1 Posted May 12, 2010 Is this size tire going to be too small? I'm adding eibach springs and tokico shocks so the car will be lower than stock. Link to comment Share on other sites More sharing options...
Arne Posted May 12, 2010 Share #2 Posted May 12, 2010 Well, I think so, especially on a 280Z. That size is the same diameter as the original 13" rubber on cars like 510's and 1st gen Rabbits. Will throw off your speedo noticeably, and gear down the car too. Link to comment Share on other sites More sharing options...
Zs-ondabrain Posted May 12, 2010 Share #3 Posted May 12, 2010 Just go with a 215 or 225/50R16. Fills the well, better sidewall for a smoother ride, wider foot print for better grip. I have Eibachs and KYB's (soon to be Tokico HP's) 225/50ZR16's And there's no rubbing, great grip, smooth ride and they fill the well without any issues. Dave Pics below show how they look, plenty of clearance without looking too small. Link to comment Share on other sites More sharing options...
Gary in NJ Posted May 12, 2010 Share #4 Posted May 12, 2010 The OEM tire, 175/78-14 has a total height of ~ 24.75 inches.What you have asked about has a total height of ~ 23.25 inches.The 175's have a sidewall height of 5.37", wile the 205's have a sidewall height of 3.63" - and they're much stiffer. The car ill ride like a skateboard.215/50-16's will fit well and have an overall height of ~ 24.50 inches.For what it's worth, I'm running 225/50-15 (just under 24 inches). The ride is stiff and the steering is heavy at parking lot speeds, but they do look good. Link to comment Share on other sites More sharing options...
280z money pit Posted May 12, 2010 Author Share #5 Posted May 12, 2010 Thanks for the info. I found some wheels I wanted to buy that have these size tires, but I guess ill have to pass. it would have saved me a couple hundred bucks, but I don't want my car to look funny.

MikeW Posted May 12, 2010 Share #7 Posted May 12, 2010 (edited) Here's one of many tire size calculators on the net that will help you determine the diameter difference (and resulting speedometer error) of various tire/wheel combos:http://www.miata.net/cgi-bin/tirescgiOops, tried to post URL of results page instead of original page:http://www.miata.net/garage/tirecalc.html Edited May 12, 2010 by MikeW bad URL Link to comment Share on other sites More sharing options...
tlorber Posted May 12, 2010 Share #8 Posted May 12, 2010 That calculator is great. Can someone verify what the original stock tire size was (or what the speedo was originally geared to?) I have read 195 60 14, 175 70 14 and a couple others. Link to comment Share on other sites More sharing options...

Gary in NJ Posted May 12, 2010 Share #12 Posted May 12, 2010 All 280Zs came original with 195/70-14Opps. I'm 240-centric and gave a 240Z size. Sorry. For what its worth, a 175/78-14 and a 195/70-14 have the exact same overall height. Link to comment Share on other sites More sharing options...
