This is a cool twelve in lift on kj.Is any one in aus doing at least a 4 inch lift.I have a 2 in ome lift.arb lockers ,now goin to a bigger tyre.I want mt's on for jambo.Can any one help with what works.245/70/16 is what my tyre service says. but interested in what other people have done

245/70/16 IS THE BIGGEST LEGAL SIZE TYRE YOU CAN FIT. You can go bigger, but, legal. No.

CRDSTU is the guy to talk to if you want more lift, Remember 50mm is the biggest legal lift for any and all brands kind types of vehicle here in QLD.

Whe going bigger tyres, you need to also think about bigger bumpstops, so as the larger diameter wheels dont rip off flares and contact body work. Also gearing becomes a factor. I stongly suggest with a V6 that if going up to a 31 (245/75/16) the pinion reset is done. This corrects the speedo, more importantly tho it corrects the info the TCM is getting so the auto transmission will be able to cope better with the difference in tyre diameter.

ciao CMOHR; just fitted 245/70R16 Scorpion ATR's all round (5) to the CRD - do you recommend the pinion reset?

We're taking it to the beach next week for our summer vacation (450km or so, down to a pretty little village called Allumiere, 500m up on the hills above Civitavecchia - near Rome), so I'll check the speedo against the Garmin but I'm interested in your comments. It's a 20 minute drive each morning down to the beach at San Augustino, down a dirt/sand track to the 'free' area.

thanks for any suggestions

With the placard stock size of 235/70R16, having 245/70R16 is the largest legal size as cmohr says. It increases the diameter to 29.50" from stock 28.95". I calculate 29.54" to be the largest legal size....well here in QLD anyway (no more than 15mm bigger than stock).

Ferraricheals - if you're worried about the impact on your speedo, check out http://www.miata.net/garage/tirecalc.html and put in your dimensions. When I put in the specs above, it says that the speedo reading will be 1.9% too slow. That is, when your speedo tells you 60mph (96.56 km/h) you'll actually be doing 61.1 mph (98.33 km/h).

I'm currently running the same size (245/70R16) and personally haven't bothered. Just factor it in when you come through speed traps!!

thanks for the feed back. but I ended up going 245/75/16 cooper STT.they fit well .and are 19 mil taller than new 235/70/16 top and bottom. from the near worn out all terrains to these it gave me 1" higher in measured lift from ground.speedo about 5-6 kph out at 100kph.traction is great esp with the arb lockers.clearance good for a kj. we did have to cut the plastic away and we bent over body pertrusion on front gaurd and sealed it up with sicflex and srpay over with body deadner.finished up nice.i will have to change bump stops eventually as the top of the back guards did rub on full articulation.but no damage and it got a good work out yesterday.very happy with the safari snorkel to.only a whinch to go now

I dont think the CRD suffers from the gearing change as badly as the V6 does. And, the CRD has a differnt Auto transmission to the V6 as well. I personally wouldnt bust a nut trying to get it changed, if only 245/70/16's.



It is now considered "Unroadworthy" in Australia to have a speedo that reads a lower speed than actual speed.

If you are worried about speed take it to jeep and they reset the speedo according to the tyre specs you are running, not overly expensive in relation to a speeding fine and the hassils that go with it.
