sdj02 Posted September 29, 2008 Share Posted September 29, 2008 I have come up with some good tires that are 225/70R15. I need new tires on the rear of my 280ZX. Can I fit these tires on the rear? I have stock suspension and the stock swastika 15" wheels. Thanks!! Quote Link to comment Share on other sites More sharing options...

luvemfast Posted October 3, 2008 Share Posted October 3, 2008 I have 255/16/45 on the rear of my car. Using 16 x 8 S14 Silvia rims and spacers for correct offset. I have lowered it 40mm wich gives extra room from mad negative camber. I would say 225 would fit the width, but 70 profile seems rather large to me. What is the rolling diameter?

gwnwar Posted October 3, 2008 Share Posted October 3, 2008 Use this site to see tire size and difference between sizes.. http://miata.net/garage/tirecalcold.html Quote Link to comment Share on other sites More sharing options...
sdj02 Posted October 3, 2008 Author Share Posted October 3, 2008 What is the rolling diameter? According to the chart I use the diameter is 27.4". I know that is tall, but with my gearing in the 727TF I need a tall tire. I was just wondering if I could stuff them in there. Thanks for all of the info!!

kiwi303 Posted October 3, 2008 Share Posted October 3, 2008 The 280Z Fairlady (JDM 280ZX) sitting in my hayshed has 225/60R15's on it now, with about 5mm between the stock suspension and the sidewall. Quote Link to comment Share on other sites More sharing options...
sdj02 Posted October 8, 2008 Author Share Posted October 8, 2008 The 280Z Fairlady (JDM 280ZX) sitting in my hayshed has 225/60R15's on it now, with about 5mm between the stock suspension and the sidewall. I know the width will clear because the 60 and 70 series are both 8.9 inches wide, but how much clearance do you have from the top of the tire to the fender well? The 70 series is about 1.8 inches taller. Thanks for the info!! Quote Link to comment Share on other sites More sharing options...
kiwi303 Posted October 8, 2008 Share Posted October 8, 2008 I'll run a tape measure through the wheel well to check vertical clearance later today when I'm passing the shed, it's 3 Km from the house up a side valley at the far end of the farm so I can't just pop out and have a look like if it were in the garage workshop Quote Link to comment Share on other sites More sharing options...
JustinOlson Posted October 8, 2008 Share Posted October 8, 2008 You should be fine I'd think. Check out this 295/50-16 (27.6" diameter): Quote Link to comment Share on other sites More sharing options...
kiwi303 Posted October 9, 2008 Share Posted October 9, 2008 I ran a tape measure from the top of the tire to the roof of the wheel well, looks to be about 8 or so inches clearance, out at the outside edge of the well it drops in to about 5 inches but looking at the suspension geometry it looks like the tire will come up inside that. You should be fine slapping the 70 section tires in, if nothing else if theres rub on the top you can slap on some taller bump stops.
