Hi guys,
Just wondering if anybody has experience of fitting larger tyres on a Prado. Stock tyres are 265/65 on 17″ rims.
I’m thinking of 275/70’s but not sure if there will be enough clearance with this size.
Also if anyone has fitted this size of tyre, what effects on performance and fuel consumption?
I’ve almost gone through the stock set of dunlops in 35’000 km’s so am also considering others brands as these don’t seem suited to my “enthusiastic” driving style 😕
taller tires will adversely affect engine power for sure!!
u might also run into steering and suspension clearance issues….
i recommend maintaining the OEM size of tires to avoid several mechanical complications.
if u wish though, u might want to go for a slightly wider size, yet maintaining the same overall tire diameter. its always recommended to try on the front side first and test for any rubbing at full steering before you buy!
heres a link to a calculator that will help in choosing equivalent tire size combinations:

Although everything you have said is 100% correct I disagree with your conclusion.
The issue I have with running wider tires of the same diameter is that you increase rolling resistance and adds unnecessary weight both of which also rob you of torque/power without much benefit as. when driving in sand you create a bigger “wake” infront of your tires. You also increase srub radius which also effects clearance, fatter tires defiantly look cooler though.
For my car I will be looking for the exact opposite, the tallest shiniest tires I can fit under my guards as they will be lighter, increase the footprint, and provide diff clearance. The rolling diameter will rob the engine off power, but meh, theres always low range
For the OP, I think the tire size upgrade sounds good. You will loose a little onroad power and off road might have to use low range a little more often. The question is will they fit in the guards? I sudgest going to a tire should and asking if you can check, throw them a couple aed and articulate your suspension and check lock to lock. Then you just have to decide on the tire model you want.

good luck with your project dean!
hope it works out for u 😉
but please keep us posted on the results!however my advice to you alec would still be to stick to OEM size and only if you need to go with 275/60/17 that will provide a wider cross foot print that will aid much more in floatation when deflated… too much floatation is not good either!! wider might put u in a bad situation when it comes to side sloping as the vehicle would now want to slide sideways with gravity rather than maintain a balanced forward motion.
the rolling resistance and additional weight that dean mentioned is true but would be negligible with a 10mm difference in width, however the downsides of a taller tire are far worse specially for light weight vehicles like the prado, since in addition to the extra weight of rubber there will be greater drawbacks with increased rotation radius that will eventually put lots of stress on the drive train, engine and suspension components…. far worse stress yet if used with low range !! you will be breaking your front diffs every so often (been there done that!!)
after all guys the choice is yours and the best way to find out is to try on a used cheap set and discover for yourself!
cheers

Very sound advice!
Although I am a person that prefers the added benefits of if a taller tire, everything in this post is 100% true (except maybe the breaking of diffs, I thought Prado diffs where rather strong and they should cope fine with that small increase….it’s not an xj jeep after all.. But taller tires do add a stress and it grows exponentially with size.
Thanks for all the input so far guys !
Still have a few ‘000 km’s left on the tyres, but will probably end up going for Yokohama’s 265/70’s when it’s time for replacement. Heard somebody here got a set at ~400 AED each. Really good price seeing as I’ve been quoted around 600 / tyre (at a special Company discount !)
Just got a lift kit installed (2″ lift approx.), Fox Suspension. Hopefully will help a little with ground clearance and maybe save the front end from a few ‘bumps’. Will probably end up getting a skid plate fitted before year end also.
Work was done at Arctic Trucks….. very professional bunch of guys and very much into Toyota, as they do a lot of work for Al-Futtaim Automotive.Will try and get out at the weekend if there is a drive after the Liwa trip…….
