Tallest wheels (not widest) on a standard 110?

Hello all, am looking to get some new tyres in the near-ish future, and am a fan of skinny wheels rather than fat ones. Most of the past advice on the group has been about how fat you can get rather than how tall. I'd imagine that a thin tyre will fit better than an equivalent diameter fat tyre, so am interested in any experiences that others have had with fitting tall thin tyres to the truck without mods.

Any takers?

I occasionally see a series 3 around here which is running 9.0x16 bar-grips a-la-101. can't say if the suspension has been altered to achieve this though.

Regards. Mark.

No chance! I've got a mountain bike and every time I've ever gone out on it, I've got a puncture. Mind you at least I've proven that the tyres can handle over a tonne of weight ;-)

These are roughly in size order.

7.50/16 235/85R16

What I'm really after TBH is the same width as my 750R16s but taller to add more ground clearance while retaining the same cutting ability of the 750R16s. The 235/85R16s are wider and a little taller if my maths is right, but not really tall enough. The 750R16s are about 30 inches diameter, ideally I'd get sommat like 33-36 inches in a 7.5 inch width. I might need a 1 or 2 inch lift for that though.

Thats not possible because tyres with this kind of sizes have a 1005 of the width-sidewall height. And there is nothing with more than 100%. Taller has to wider. Smallest taller size is 9x16 or the aequivalent,

255/100-16 (Michelin makes them)

No, they are exactly the same diameter. I change tyres quite frequently on my Land Rovers and often have them side by side to see the same diameter. The Michelin XS in 750x16 on a 6,50 mangels wheel for instance are also exactly the same width as my BFG AT 235/85-16 on the wolf wheels.

The american tyres where you can roughly choose width and height are mostly 15 inches.

To go higher but stay with 7.50 width, you will have to go to a larger wheel diameter - you will be looking at custom wheels. I can't think of any recent cars with 17, 18 or 19 inch narrow tyres, but you may be able to find ones made for vintage cars (but they will be cross plies with on road tread). However, to get any choice you are looking at 20 inch - and at that size you are talking major body and suspension mods, although it has probably been done. JD

OK, so I'd need new wheels at least, that's not so bad and what I was expecting. I get the feeling though that my choices in tread pattern are likely to be very limited if I want to go narrow!

I measured mine at 30 inches diameter and calculated the 235's at 31.5 so the 1.5 inches I'd imagine is well within bounds of squashing and minor measuring point changes, I've never had the opportunity to compare them in the flesh as you have done.

So do you know of any tyres that are of a similar width but a little taller? Something like a 235/100/16 (if I am getting my tyre sizes right)? Or even 235/85/rim larger than 16?

Is that a 15 inch rim?

There are so many different measurements and measurement systems involved that I have to confess to getting them a little confused at times so sorry if I seem a little sideways..

Not sure what you mean by 17, 18 or 19 inch tyres, I'm assuming you meant rims rather than tyres?

20 inch what? 20 inch rims? My current rims are 16 inches diameter, my tyres are 30 inches diameter, I'm not sure where the numbers you are quoting fit in.

I've seen some hulking great big tyres put on a landy with Volvo C303 portal axles, that was a mighty beast ;-) The axles added about 4 inches of clearance themselves. A little too much modification for me really, I don't mind adding 1 or 2 inches lift.

I personally know of no tyres with metric sizes and 100% height to widht ratio other than the aforementioned Michelins.

Yes

it is confusing ;)

Yes, the numbers I referred to are rim sizes. The point is, as tyres are not made with height to width ratio more than 100%, if you want to go to larger diameter with the same (7.50) width, you will have to go to a larger wheel diameter. But tyres with 100% ratio and rim sizes between 16 and 20" are (well and truly) obsolete so choice will be very limited. 20" is a standard truck size, but 7.50 is at least obsolescent, and, again, your choice of tread will be very limited.

Maybe you need to talk to a tyre supplier about options, but I suspect you will find that there is not any practical way of doing what you want. JD

[quote]The 750R16s are about 30 inches diameter [/quote]

depends on the tyre manufacturer as well. I`ve just fitted a set of firestone SAT's 7.50x16 (yup, i found a set that weren`t all cracked and knackered, like rocking horse pooh!) I rolled them towards my vehicle past the project rangerover which is wearing 255/85 tyres. These are 33" diameter. For some reason the firestones are the same diameter! i couldn`t believe my eyes at first, so i got my tape measure out and the diameter measured in at 33.4 inches!!!!!

that ain`t bad for a 7.50x16 By the same thing, my avon rangemasters were a 7.50x16 and measured in at 31.2 inches. Dunno if its just the tread depth that makes the difference or if different manufacturers use different construction techniques giving different overall diameters.

Blimey! These tyre sizes are a real PITA. Some kind of link to reality would be nice. Perhaps they're swelled up with water like bacon ;-)

Then again 750R16 only specifies that it's 7.5 inches wide and fits a

16 inch rim, so doesn't specify sidewall height I suppose.. That's if these bonkers measurements are what I think they mean.

I'm beginning to think tyre manufacturers are just a bunch of loonies!

Well according to the second link previously posted imperial tyres don't state the section ratio and it is *assumed* to be 100%. But you know what assumptions do, they make and ass out of u and me...

Haven't struck this with 7.50 tyres, but I struck it a couple of years ago trying to replace a tractor tyre - only way I could get one close enough to the same size was to get two, and sell the good one to the retailer, who happened to have a tractor the same with mismatched tyres! So I am not surprised.

I suspect that in some cases the 7.50 refers to the size of the space the tube fits in, so the thickness of the belt and tread is added to it, where other manufacturers reduce the size of the tube space to allow for the tread and belt thickness to keep their tyres the same overall diameter. Same probably applies to other sizes. Last night I looked up the steering stop information for the 110 - and found that the stop setting depends on the brand of tyre, as well as the size! JD

There are two lots of 7.50-16s around: the cross plies and the radials.

The Firestone SATs are cross plies with an aspect ratio of about 100%. The Avon Rangemasters are radials with an aspect ratio of around 80%.

Hence the SATS have a larger free outside diameter.
