How big is too big?

[MudSlut]

Hi, I see a lot of 4wd's running 31"/33" tyres and some running 35" tyres, apart from cost and a higher chance of breaking something is there a good reason why everyone doesn't just get lower gear ratios and 40" tyres?

I'm asking this because I'm looking at getting the GQ some new shoes and rims, I have my eye on a set of Pro Comp wheels that are 15x14 with a offset of -89mm. and running a 40x15 tyre. I already have 8" of lift and the offset should keep the tyres from hitting the chassis, The GQ is mainly used for 4wding with the occasional HWY run, I will be keeping the 35's for any prolonged HWY use.

Wouldn't the main concern be a strong wind blowing it over.

All comes down to the boys in blue mate. I would love to run a bigger tyre. I have 35's and am very cautious of them.

totaly agree im sure most ppl would run larger but over 35" is prity damn obvious that they arnt legal they will prob hear the tyre noise b4 they see your rig ! haha but if u dont care for gettin stung go for it whats the fine $ anyway ?

Oh ok cool, well here in Tas they are pretty relaxed about laws... O.o I know right! I see a lot of rigs with tyres hanging 2 or 3 inches outside of the arches and jacked up to the tits, The cops don't pull over anything apart from imports. even stock Imports, everything else just falls into the "Not a Hoon" category and gets overlooked.

Modification is one reason even with your lift you will probably find some sort of clearance issue with your guards, as you said big tyres put more stress on everything to get the size working at its best for you you will need crawler gears and a diff ratio change. GQ cvs will pop depending on your driving style so you will need to upgrade these to chromo or gu front diff, diff will have to be braced especially running such a wide tyre and big offset wheels. I love bigger tyres but make sure you put the work in or it will spend more time trying to break itself

[MudSlut]

Ok thanks nissannewby, I'll have to look more into these upgrades. I don't mind spending the coin if it's going to better the off road capabilities.

IMO the 8" is too big, unless you are changing the diffs to 'full size'.
