Outer Limits 4x4 Board

im runngin 15x7s now and buying brand new tyres and thought maybe going to 16inch rims and tyres would be a good idea

just wondering your thoughts

im running 33 x 10.5 x 15 so i have alot of side wall and thought maybe reduce it by running 16inch wheels.

16 inch wheels are more expensive, one negative, but you normally open up your options for tyre sizes too. Less sidewall means better control but more wheel to destroy on obstacles.

Question is why do you want to go to 16s other than reducing your sidewall height?

I'd only consider going to a 16" to fit the 35x10.5-16 silverstone extremes.

33s 10.5 x 15 only one brand makes them bfg and there expensive
more tyres to choose from in 16inch and less tyre wall
plus i can run most of my mates tyres cause there all running 16s
just if im spending 1500 might aswellupgrade to 16s
new patrols and more are now running 17s and up
this is crazy

by running 16's the tyres also "look" smaller thus not attracting "as" much attention from those we wish not to.

Find the tyre you want to buy. Then find out what rim you need to suit that tyre. Idealy let the desired tyre dictate your rim, dont choose the tyre just because you want a 16" or 15" rim. If the tyre is available in both sizes then worry about it after you know the price difference between the two.

I think you are mistaken. 33x10.5x15 is not that uncommon.
Couple of others in 33x10.5x15:
Silverstone MT-117 Extreme
Simex Jungle Trekker
Radial TSL
TSL Bogger

This list is rather unsorted and incomprehensive and made up of more aggresive type tyres, but makes the point that there are other tyres in that size, even though the 33x12.5s are still more common.

silverstone extreme dont make them anymore they had too many problems with there tyre holding air i was told by silverstone themselves

simex do but there twice the price and they acually measure over a 34ich so thats not good for me lol

havent seen boggers or swampers but frommemory only 11.5 or 12.5 in width plus i dont think there road legal anyway

thanks for your help though highway star

You sure about the Silverstones? They still list them.
Simex: Fair enough for them
TSLs: Check this out http://www.intercotire.com
apparantly the boggers are legal but the Swampers are not or something annoying.

Just keep looking and asking around. There are bound to be a few more.

Chapel Corner have ceased importing the 33" size as there were too many issues with that size only.

The 35x11.5-15, 35x10.5-16 and 31x10.5-15 are the only sizes available in Aus at the moment. These are selling strongly with many happy customers.

OK, 2 against 1. Thats dissapointing. I own the 31s, bought them about 8 months ago and the 33s were still available then.

Tell me about disappointing! We have more inquiries about the 33s than any other size!

Dan

shit 8months too late damn it
if i have to ill go bfg but would prefer an awsome aggressive tyre
just got qutoed from procomp 125 per rim for 16x7 thats 500 a set just for rims ouch
whats the equal size in 16 for a 33 10.5 15
i know a 285 75 16 is a 34 so whats down from there

Stock Tire - 285/75R16
Section Width:11.22 in - 285 mm
Rim Diameter:16 in - 406.4 mm
Rim Width Range:7.5 - 9 in
Overall Diameter:32.83 in 833.88 mm
Sidewall Height: 8.41 in 213.61 mm
Radius:16.41 in 416.81 mm
Circumference:103.1 in 2618.7 mm
Revs per Mile:633.5

you'd be right with that size mate.

we've found the MT117 sport to be a far better tyre for all conditions over the extreme. out in tracks you couldn't really spot the difference in performance on two similar zooks.

Its just that the sport is not available in the 33x10.5 like wideaz is chasing; they have the 33x12.5. If you go the 16" rim, the most suitable size is the 285/75R16 (size mentioned above), which is still ~11.3" wide, it depends how fussy you get on width, personally I think thats on the border of too wide, buts thats just my opinion.
Ive never used the sports or seen them in action; but I must say the Extremes are at their worst on gravel roads, just so little sideways traction, its like ball bearings sometimes.

I am actually surprised at how many tyre companies makes 12.5s and not 10.5s in 33s now that Ive had a look around. Some other metric 16" equivelents (if they exist):
255 x 0.85 R 16 (33 x 10)
265 x 0.80 R 16 (32.7 x 10.4)
275 x 0.80 R 16 (33.3 x 10.8)
275 x 0.75 R 16 (32.2 x 10.8)


If people want to calc metric to imperial tyres it easy, I'll use a stocko Sierra tyre as an example (205/70R15).
Carcass width is the first number, so 205 = 205mm. divide by 25.4 = 8.07"
Sidewall height = width x profile. 205 x 0.7 = 143.5mm = 5.65"
Overall height = Rim + 2xSidewall Height = 15 + 2x5.65 = 26.3"

Can any one tell I'm pretty bored
Have fun...

Keep an eye on load ratings in the 16in sizes as many will be far stiffer in the sidewall than the 15s and arguably, may require more weight/less pressure to make work on a zook. That said, 16s provide some great taller, narrower tyre options.

Joe, how do you find your 285s in regard to load rating? Is your LWB 'that' much heavier than say a stripped out SWB? What pressures are you at?

How recent is this information about the Silverstone mt117 xtreme not being available in 33x10.5-15 anymore?
I order a set two days ago. They arrived and were fitted today.
Top looking tyre. Can't wait to give them a run.

i'm running about 18psi on road and off i run about 10-12 depending on my load. the sidewalls are fantastic and very compliant. will see if i can dig up some pics of the tyres in action.

Cheers Joe.
