Outer Limits 4x4 Board

hey all, looking at these 2 tyres,

or any tall NARROW tyre,

must be 16 inch..

my question is if these 2 tyres were mounted on a 7 inch rim what is the actual dia/height and width at its widest, cross section???

cheers, serg

I'll measure my Q78's tomorrow. They're mounted on 16X7's.
Q78's are taller than 35" simex's and tougher. Simex's are better in sloppy mud, Q78's are better on rock and rutted terrain. Slippery stuff i reckon they're on a par.

cheers mate, this is the sort of feed back i want to here

also how are they both on high way/road driving?

not going to have them on all he time of coarse...... but how do they go?

A Q78 on 16x7 mechanical beadlocks measures at 35.5." tall.
I've had both and prefer the swampers allround.

Hmmmm.. On road, simex's all the way.
Swampers are fair pigs when they're cold, they do get better with a bit of temp in them but you cant beat radials on the road.
I'd prefer to put up the swampers on road though for the benefits you get off road.

I reckon the simex's are noisier than swampers too.

I have seen some simexes do some great stuff on clay etc, but I'd never own a set. I've had 4 sets of swampers though and LOVE Q78's.

thanks guys,

im not to concerned about the height but want the narrowest of the 2

so which is narrower on a 7 inch rim?


cheers, serg

I'd say the 78, but can't be sure.

PS they will go on a mechanically beadlocked 6" rim too (so effectively 6.5") and they sit very nicely- they look really tall and narrow like that.

any photos of them fitted to 6's?

why does everyone refer to them as Q78's. Is that not the load rating or something of the like.

because thats what they are called, u can get them in 15 or 16 inch rim size...

have a look at interco's web site

The swamper come like this
35 TSL
Q78 TSL
36 TSL
Don`t know why Interco called them that but that is what they are. Its like everybody is just calling a 35 or 36 TSL swamper a Q78

well im refering to the ones of there (interco's) chart that are called Q78...

there is only 2 available one in 15 inch rim and 1 in 16 inch rim

ok so those sizes i posted tell me it has a tread width of 9.5 inches or 241mm and a cross section (im guessing thats what c.s. stands for????)
width of 10.8 inches or 275mm

does that sound right?

how much difference to width would mounting them on 6.5 inch rims over a 7 inch rim make???

the simex i saw/measured that were 35 10.5 16 were 10.5 at the tread and 12 or about 305mm at the widest point (cross section)
