285/75/16 on a 100s cruiser?

Damon,

Darkie has this size in the infamous Cooper ST's ;)

The speedo reads just over ie reads 100km/h but actual is 103km/h.

Cheers Kev

Hi mate,
I only run285's on my cruisers. The speedo reads 95kph when I'm doing 102kph.
You do lose a little bit of power due to the overgearing but not that noticeable.
They handle fine but that is BFG muds. Just keep in mind that a larger sidewall will flex a little more before the vehicle responds to the steering input (i'm talking about a fraction of a second).

But they get the diffs that little bit further out of the mud and that's a good thing.

I don't know how well they clear the guards on an IFS as I only use rigid front axle vehicles and no probs with a lift.

Regards
Dave

Same as the others....when doing 100kph really doing 107kph....

Slows car down a little but goes well other than that....we did over kill i think and had the cooper stt's in that size...over kill the bank account that for sure!

I use 265s , even at that width you have to be on the ball if just one steer wheel hits a large puddle, be ready for instance correction.


.

I have the 265 Cooper ATR's at the moment but at 40 psi i find that there is a lot of bulge in the side walls I'm curious if the 285's will be better or worse( Toyota 16x8 alloys).

I have 285/75/16 Cooper STT's on my TD100. They are mounted on standard Toyota steel rims. I also have about 2" lift with OME suspension. I don't know if they would fit with standard suspension.
My speedo is 4% low ie speedo shows 100, I am doing 104.
Handling and general behaviour on the road is good, but I really have nothing to compare it to because I fitted 285/75/16 as soon as I bought the car. The first set were ST's, and they handled good too.
Cheers

We run Pro Comp 305 70 16 ATs on our 100series and the speedo is about 5kph out, 35 in front and 39 in rear due to (as Pud says, all that STUFF you have in the back) and have had these since vehicle was new and handles like a dream.

100 series GXL BFG 285/75/16 on Toyota ali wheels, 31psi front 32psi rear, good ride and had them on for just over a year now and no probs, have not done any real muddy stuff as yet, had the standard Dunlop grandtreck before and cant say notice much difference when driving, spedo out a bit, when showing 100 actual is 1004, hope this helps.

Thanks Al, pleased you noticed, those tyres make a heap of difference ah 1004 klm and still going, ok just maybe I made a little boo boo, should that have been 104, have to get onto Mythbusters to sort this one out. Pete

My 285/75/16 Kuhmo a/ts make it 5km out and the 305/70/16 muddies are 4km out on my 100 series.i will put a speedo corrector on it,honestly!(been saying that for 4 years LOL)cheers Paul

have 285/75/16 bfg muds fitted to 04 td ifs with approx 45mm lift on front and approx 50mmlift on rear-when suspensiion fitted.
if you drive on these then change back to standard grandtrek rd tyres(16inch for 04 model) there is a huge difference in power take off.
suspension sageed a little on front each 12-18 months and on full lock there is rubbing of tyre up front(need to adjust front height again).
handle better in bush over obstacles and ruts etc in my opinion and woth the extra diameter. certainly at 100 i am doing more than 100.
certainly in my opinion and experience from a 100td ifs the extra height gained with 285/75/16 from standard size road tyres is worth it-not sure how much taller these are from your current tyres of 265/75/16.
cheers

Damon,

Another one who runs 285X75X16 BFG muds now with 70,000KM and still a bit to go. They have done a fair bit of outback touring. Speedo is out about 5% as others have said. I have the ATS 4X4 2" suspension mod. Even so I have had the rear tyres scrub the inside of the mudguards on full articulation. Handling is great both on and off road. I run 40psi on the blacktop.

Look here and you can work it out for yourself exactly

This last one is really good as it allows you to compare rims and offsets etc so that u can try new combos for your wheels

Thank you to every one for their replies.
