37s on the 80

Post by **guzzla** » Thu Oct 11, 2007 11:10 pm

The mighty 80 is engineered for 35s and ive been running them for a while but im playing with the idea of having a road set and off road set though the off road set will still be a radial tyre ie MT Claw etc

Ive got a 5-6in lift plus 30mm BL so I think they will fit without spacers but im keen to hear from those of you who already run 37s as to wheather they are worth the extra moola over 35s and any complications using them on your cruiser - bearings / cv's, cops and RTA etc.

thanks in advance.

Couldn't believe the difference 2 inches makes. (There's a sig line) The difference between 37s and 35s offroad are very noticeable. I won't go back to 35s as the 37s (MTRs) drive ok on road as well. Why a radial tyre if it's just for offroad? If you have the dollars for two sets you might as well go bias for offroad. Can't help you with the info about an 80 though, but you have more than enough lift.

Give a local bloke here a PM, Hardcorr, I think is his nic on OL. Otherwise email him here http://www1.freewebs.com/hardcorr/ He is running 37's on an 80.

I was running 40's under my 80 with only a 4in lift (and a little trimming

), so 37's and 6in should be no grief at all.

They sure do fit ok.

Do you guys use your trucks as daily drivers with 37s and have you had any issues with the law / rta etc

Can i get away with running 37s in 8in rim or do i need a 10in ?

keep it comming as there is bugger all in the archives on this topic.

Thanks again

If your sticking with a 12.5in wide tyre, 8in rims will be perfect. I had the 80 engineered with 35's, and the guy listed the 40's as "off road" tyres and gave me a placard to say the same. It was my daily driver as well. I recommend changing ratios to 4.88's, and while your at it, fit a solid spacer on the pinion instead of the junky collapsable job.

Mines a daily driver too, and I drove it 1000kms per week for 2 1/2 months this year going to the snow (at highway speeds). It's engineered for 35s on 8" rims so no-one really notices they are 37s on 10s. I only went the 10" rims back when I was having issues with steering shimmy (it was only on 35s back then too) but the 37s work fine on 8" rims.

My 37s also fit with a 4" lift and no body lift.

If a car is engineered to run 35's, does that mean you can legally run 37's (+50mm diam rule)?

Long shot i suppose

Thats the best effort Ive seen at finding a loop hole in the fine print!!!!

I see your angle but i doubt it would work.

I forgot to mention that I already have 4.56 gears.

what ever you have engineered you must run that only anything diffrent and you can be defected (if they pick up on it).

My Hummer replica is licenced as as Individually Constructed Vehicle, my registration says it's a 2006 dual cab utility (other states class them as a re-body and they are licenced them as a Nissan Patrol) and my tyre placard says 35inch tyre and 15 x 10 rim, it is listed on the RTA's system as having a 35 inch tyre as standard fitment and the RTA says that I can leagally go 2 inch over to 37's

Cool might have to buy your ICV and do a body swap and put a patrol body on it.

Ive noticed that alot of the comp wheels and tyres are being made in 17s and sometimes only 17s.

What is the purpose or benifits of this.

Cheers.

Manufacturers angle their design to capture the most sales. These days, rockcrawling is heaps popular, especially o/s.(Aus doesn't rate a mention)
So....a tyre that has less sidewall will stand up better on sideangles at low pressure and remain 'soft' in the tread to maximize grip and minimize damage. The spin-off is that radial 17's will (generaly) handle better on road.......

me thinks........

open to other opinion.........Dave
