Hi, Can anyone tell me what the maximum tyre size you could fit on the
standard 80 series 16in rim would be. Looking at purchasing 285/75r/16. Was also told 315/75r/16 would fit, but that sounds rather large to me.
Any
feedback would be greatly appreciated.

The 315/75R16 will fit on a 16X8 rim. Don't know if they will fit under the 80 series without a lift though.

Pappas ... According to ADR guidelines, the largest size you can legally go to is 20mm wider and 15mm more in overall diameter than the largest tyre on the vehicle's placard. This is NSW's RTA interpretation of these guidelines -

Use this website to work out the dimensions of the stock tyre and the larger sizes -
http://www.miata.net/garage/tirecalc.html. This will give you an idea on what you can fit and stay legal.
It will also avoid insurance hassles if you are ever in the unfortunate position of having to lodge a claim.

Go larger than 15% of original size then you need an engineers Cert.
EG if it comes with 31's and you go 33's you need engineers cert. Dan got a price of $230 to engineer his tires, so he went 32s instead.
Remember if you have a crash or anything with too larger a tire on, your insurance can wave tut-tars to you... and then your in the brown stuff.
Thats where I would start asking!
If your in
Melbourne call this Engineer, he is the one we all use.

Truckster,
How much does he charge for a certificate?
The BFG AT 265/70 R16 = 30.7 in
The BFG AT 265/75 R16 = 31.8 in
The difference is about 28mm?? So why did Dan go from the 31's to 32's; are they still not exceed the 15 mm limit.
I actually called VIC Roads before I got my tyres fitted last week 265/75 R16 instead of the OE 265/70 R16 and told the guy at Vic roads about the 15mm issue that NSW Road has with tyres. He told me as long as the tyre rating is the same or better then its legal. That is in contradiction with the link that was posted on this thread.

Luke... just asked Dan on ICQ.
Diameter increase of more than 15mm needs eng cert
31 -> 31.5 ok
31 -> 32 not
$240 for engineers on the tires, too much for only 1" more
Go 3" more prolly worth it
