Katherine, I have an '03 GLX... When I got new tyres, I was told 225/75-16 was the largest I could safely put on the 6" standard rim. I have 31-10.5-15 muddies on a set of 7" sunraysia's, they fit
well and don't scrub anywhere. the 15x7 sunraysia's were about $50 each.

Thanks for advice, after reading your response and doing a bit of net surfing 225/75R16 AT is probably my best opition (without changing rims and keeping my insurance company happy).
Thanks

Hi there
Its been a few weeks since i asked the question re triton tyre sizes.
Been thinking about what you wrote and have a few more questions.
31/10.5R15 (774) vs 225/75R16 (744).. 30mm hieght difference in O.D
When running 31's is the speedo affected much??
We also own a GLX which doesnt have flares, do the 31's stick out much past the guards??
thanks

Hi there
Katherine,
Best I can figure is about 5k's out. Driving next to my wife(she was in our Falcon) She sat dead on 100kph and I was almost spot on 95kph on my speedo. Using 5kph as a rule of thumb, I have managed to avoid any speeding fines, although I only have the 31's on 4 or 5 times a year and rarely for more than a week or so.
I think someone posted a %-out calculator for increased/decreased tyre diameter a while back, might be worth another post, in fact I'll get on it right away...

assuming its only a 6 inch rim?? i would go to a 7.50 r 16 you can get some good off road tyres a bit cheaper wit this option

forgot to mention that the 7.50s are equivalant to a 32 inch tyre

Quick calculation. 205/80 16
16" = 406mm
205 * 0.8 = 164mm - *2 = 328mm
Total OD = 734 mm
In theory you can only legally go up 15mm in diameter = 750mm OD
= approx 29.5" OD
(There are some on this
forum who will debate this 15mm figure)
225/75 16 would work at 743 mm OD
I run 235/85 16 on 16"x6" rims - 805mm or 32" OD, which is about the biggest tyre you can mount on that rim.
7.5 x 16 ( = 190/16) is a little narrower, easy to get, and 32" OD.
Don't you love this mixing of metric and imperial in tyre sizes !!!
