Got (or want) bigger tyres? Come in here!

Unread post by Nemesis » June 4th, 2011, 12:23 pm

Okay guys, we need your collective experience for some research on the mighty DMax

What we need to know is whether you have 33" tyres, or managed to squeeze 35" tyres under your Isuzu.

If so, how much lift required to do the job? Spring lift? Body lift?

Unfortunately, knowing your brothers mates cousins second best mate apparently did x" for x tyres won't cut it. We need facts if possible, what lift fits what tyres, guaranteed.

Your proven advice will go a long way to helping a lot of people!

Cheers

33's are possible with suspension and body lift and a little guard trimming. The new superior kit apparently clears 33's but a bit of trimming is still required(from what i have read). Dont think it is possible to get 35's on them without doing an SAS. Despite some reports saying that running 33's affects steering, I have had no dramas since I removed the Snake Racing Extension. The problem you will have is the steering shaft rubbing on the steering shaft (Turbo Diesel only) when you do a body lift. This can be rectified by either going with a maximum of 40mm body or placing 10mm spacers under engine and gearbox mounts but that is a mission of a task.

From my experience 32s = 2" susp lift
33s = 2" susp lift 2" body lift
35s = SAS

This has been covered fairly extensively throughout various threads on this forum. Seems us Dmax/Colorado/Rodeo owners are keen to find anyway we can to fit bigger tyres. :D

Hope this helps

I am not sure what diameter my tires are but I have 265/65/R17 profile tyres on my dmax. I required a 2" lift and a few minor inner gaurd mods to the front.

mine is a ra rodeo so basically the same, and im running 265/75r16 (32's) on mine with only the front tortion bars would up 1 turn and minor trimming of the front mudflaps (put tyres on and have someone turn the wheel its obvious where they rub) and trimmed the front in the inner gaurd a bit as when you fit a bull bar there is nothing for the bottom of the gaurd to attach to so it can get caught on the tyre.

hope this helps.

can any of the guys with 265's let me know how they affected fuel economy in average kms per tank, i fitted maxxis bighorns to mine and my average k's went from near 700ks per tank on the stock tyres down to 500 odd ks per tank with the maxxis

I am technologically disabled and this forums new photo restrictions mean you have to resize them. That is well and truly outside of my skill set.

That is a big drop. I dropped between 60 and 80 kms a tank when I went to 265's but 200kms is huge. Something seems wrong there. Dont really know how it could have such a big effect fuel economy. I get 600 - 650 with 285 but I do have a chip and exhaust.

Is power down much or is it just economy??

Ditch the dealer and take it to a mechanic you trust. I have never had a good experience with a dealer and they really dont seem to care too much once you start changing things.

had a look under the ute today, dropping the front diff doesnt look like much of a task, just some 20mm spacers put in would do the trick i reckon,

Don't forget your odo won't be reading the same with bigger tyres. Normal to have a bit of power loss with big tyres but a 200km difference per tank sounds wrong. What tyre pressure are you running?

Howdy.

2008 rodeo 4x4 dual cab 3ltr CRD

fitted 265/75-16 = 32's

Fitted with no lift, only minor scraping on mud flap , minor rework of flap would fix this,

Am running a rapid chip and big exhaust and was getting 9ltr-100k on standard 245/70-16 tyres , did 250 k's highway cycle on big tyres and used more than half a tank,
in 5th at 100kph , not enough revs and to much throttle to maintain speed, scangauge saying 13-18 ltrs-100k

Will need to adjust driving style to minimize fuel consumption and maybe up the pressures for road from the recommended (bob Jane T-marts) of 38psi, max load is rated at 65 psi. I ran 50 psi with the standard tyres which helped highway economy .

It has given a good inch lift without andy mods,

I may try a torsion turn and a shackle lift at back,

no power loss but engine is working harder to turn more mass so can feel like less power,
