15" rims or 16" rims?

not sure what size rims to get, i like the look of the 15" rims with big tyres. but alot of people i know have 16" rims also with big tyres.

on the 15" rims is the tyre slightly bigger to make up for the lost 1"? or will the ride hight be slightly lower because of the rims?

i want to combine these rims with a 2" lift, but now im wondering if its worth getting 3" lift?

dont worry about the rim size. make your tyre and tyre size choice 1st.

there are plenty of 2" lift threads in this section so have a read. personally i wouldnt go 3" as you start to really mess with angles and things will wear faster. even with a 2" lift you looking at replacing your UJ's more often that normal.

so go for 2" and make your tyre choice. you will be able to get up to 33" with a 2" lift and poss 35's but ask a specialist dealer about that. you dont say were your from, but Devon 4x4 and the guys at the O.E.C are really good.

if your going bigger than 265's then the rims will be 15inch. tyres at 265 or smaller are usually 16"

there isnt really a general advantage in the 15"rims other than you can run them at lower pressures and increase your footprint when offroading... but thats if you can be arsed to keep deflating and reinflating... which i cant.

what tyres were you looking at? and how much $$$ do you want to spend?

Right, 15" rims with say 235/85 tyres will be 1" smaller diameter overall. 31.5" wheels are the same overall diameter regardless of the cut out for the wheel rim. Comes down to cost really, but I would go with 16" rims as that's what I've always used.

Regarding lift, 2" lift is about right with big wheels, but a 3" lift makes the car even more unstable when off-road, plus you will need castor corrected radius arms and you'll need to replace propshaft UJ's very frequently. I would stick withh a lift between 1" and 2" as there is enough clearance to stop the wheels fouling the arches and exhaust backbox without making the vehicle too unstable. If you've got a roll cage/bikini front, the top heaviness and unstability is compounded further.

i dont think you can get 15" on 235's can you? unless their road bias tyres.

what oyu after AT's or MT's?

om from north yorkshire,
as for tyres i want MTs
for wheels and tyres i want to spend up to £600

thanks for your help so far

You need to decide first what your overall diameter needs to be
I would suggest 265/75 16 in BFG is a pretty good choice for on and off road giving good mileage life and on road grip. They are also stronger ply wise in the side wall than most others . There is not really any point in going to 15 wheels as you then need to get an inch back for under axle clearance that you didnt need to give up in the first place. There is a full range of sizes in both 15 and 16 available. JMHO

shirley the overall dia. he ends up with will be the same if it 15" or 16" dia wheels?

How did you know my name was shirley? I suppose now the secrets out I will have to live with it
The point I was trying to make that to get the same under axle clearance you will need a bigger tyre section/aspect ratio in 15 than in 16 which then brings in other considerations such as more clearance needed for a wider section tyre, bump steer, component loading, etc. HTSH JMHO

p.s. please dont reveal my other name as it could reveal I am subject of a fatwah

best yer try again cos what yer sed was '"decide on overall dia" then yer sed that if he used 15" wheels he'd lose a inch of height which just dunt make no sense

Ok if you want to split hairs going to 15 rims will give you half inch loss of clearance under the diff compared with a 16 inch rim and you will have to compensate by using a larger section tyre taking into a/c aspect ratio, if the guy has difficulty understanding that ia am sure he could say so himself, hope that this has cleared up any problems you are having with the concept

so a tyre of 265 on a 15" rim will be an inch shorter overall than a tyre of 265 on a 16" rim?

i might not have owned a car for very long, but this sounds like boll-ix.

stu, the only thing you have to do is decide what size tyre you want and what pattern. i suggest you look at BF goodrich MTs in 265s, or 33" also worth considering are procomp MT's again 265 or 33" khumo do a nice MT as do Pirelli (scorpion MT) and the copper stt are also good. again either 265's (fairly big but still pretty standard) or 33" look meaty and increase your ground clearence)

the 33's and up WILL be on a 15" rim... but that dont matter a ****.

G

so you would recomend 33" rather than 31"?

also some of the tyres i look are say



31/1050R15 BFG Mud Terrain

i take it 31" is the hight, 10.5 is the width? 15 is the rim?

if so whats the 10.5 bit? is that 10.5" wide?

Toyo aren't too bad either and not to pricey.

no-ones splittin hairs. you wur saying that he needs to decide what overall dia. he wants...you then say that a 15" wheel will give you 1" lose of height. which to a complete novice in the tyre world would sound like any 15" tyre is shorter than any 16" tyre

you just dint make any sense. folk that understand about tyres and such might be able to decypher yer post . but someone asking questions about tyres is unlikey to know WTF yer on about. so if yer gonna offer advice to those that need it, do try and make it sensible and easily understood by those what ask.

you just answered your own question stu... yes 10.5 is the width tyre size is all about preference. a 31" is about the same as a 265.

265/75/r16:

265 = overall diameter
75= percentage of overall diameter expressed in width
r16= rim size

31/10.5/15 is exactly as you said it. that size is roughly equal to the 265/75 mentioned above except the rim size is diff.

31's are ok, but i like the look of 33s and the ground clearence they offer

G

im fairly sure your wrong there griff.

as far a i under stand, a 265/75 R16 breaks down as follows:

265 is the width of the tyre in mm.

75 is a percentage of 265 that the tyre is, from the rim to the outside. I beleive this is called the aspect ratio. So it would be 198mm from the rim to the edge of the tyre.

and R 16 means Rim 16 (inches), although I have also read that the R stands for radial so it is telling you the tyre is radial rather than crossply. Im not sure which is correct!

bollix! i got it the wrong way around your right mack. but a 265/75 is still roughly the same dimensions as a 31/10.5 cos i just took off my grizzly claws and put on some BF goodrich. the BF's are a little smaller in dia.

G

I was a tyre dealer for 15 years so I dont talk bolix , I have been using Land rovers of all sorts for work and play for 40 years in differnt parts of the world , so when I give an opinion I base it on actual experience, it upto people to make their own minds up.

A 265/75 r16 tyre will be 265mm section width when mounted on refernce rim the height of the tyre from rim to road will be governed by the aspect ratio stated (75%) The rim dia is given as 16 the R expresses that it is of radial construction . Therefore it will be understood that a 16 rim dia tyre of 265/75 will be ''taller'' than say a 265/70 also 16'' and also a 265/75 r 15 this is due to starting with a smaller rim size of 15 inches so therefore will be approx 1/2 inch different .
A 31 10.5 r 15 is indeed 31 inch tall (approx) the 10.5 is the section width this is on the US system and is in inches so not directly comparable . but is a bit easier for tyre ''height'' comparisons, with other US system tyres eg 33/10.5 or 33/12.5 or 35/12.5 HTSH

Thas funny all me mates that sell tyres talk bollix so I fink you must be the odd one owt
