Hey Guys

Just brought a TJ 2004 model, 5sp manual, 30,000klms on it with hard top and soft top, its great, fun car, but the fuel economy is woeful at present! 18-20 litres per 100klms (the wife driving it to work - only been checked once too but we are taking it on a trip this weekend so will know more).

It has mud tyres on it, bf goodrich LT235/70, 16" but i think im going to get road tires fitted to try to improve the fuel economy. i think the rims are off a cherokee (maybe).

Do you guys think sticking road tires on it will help with economy? Im not sure but i dont think there are any other mods.

Welcome to the wonderful world of Jeeps.

18-20l per 100km, sounds like the go pedal is normally firmly planted into the firewall...

put road tyres on it i dont think will make much of a difference, not in that size anyway.

check tyre pressures and what not, that always contributes.

dont expect fantastic fuel economy out of it (your a dreamer if you think you would) but 18-20L is alot more then what a wrangler should be using.
sure city driving you will get worse, but thats too much.

you would expect 15-16L and about 11-14L on a good trip.

but experiment around with it - and see what you come up with.

yeah i was expecting in the 14-15 range! The missus may be driving it with more go pedal than is needed too!

Are the mud tyres worth a bit? Im thinking it might be worth sticking them in the garage and keeping them for the time we do a trip that warrants them rather than wearing them out on a daily commute. Not looking forward to paying for a new set of tyres a few days after picking it up tho i can tell you!!!

Tyres depends on size and brand but round the 300 mark each

Poor fuel economy sometime comes from a 02 sensor on the way out could be worth getting a good service before swapping tyres

Come along to the sydney Jeep club tomorrow if you want to chat to a few jeep owners

Fair enough, sounds cheaper than new tires too (maybe!), ill have al look for details about the sydney jeep club and see how we go! thanks again. Should i get it serviced at a jeep dealer or is there someone you recomend? Im in cronulla.
