i have a set of 15x7 steel rims and I'm wondering will 30x9 tyres fit or will they be to skinny

[89_tintop]

No they wil be sweet

[appsie]

they will be fine mate,im sure everyone would run 7s with 30x9s

a mate even had them on flipped 8s and never had a problem,guess he never aired em down to low

[alien]

sounds spot on to be also.

what are you getting thats 30x9?

as for 15x7s, check these out:

theyre -38 offset =P

otherwise, speedy desert rats are cheaper and -15 offset:

i got 30x9.5 on 7inch sunnies. all good.

what about 30's on stocko Sierra rims?? will i have to ditch my chromies to run 30's ;( lol

[alien]

i'd say so... much more than a 235 and you want to change rims... 235 = 9.25" wide... given a standard rim is 15x5.5 even that is pushing it. 15x7 is good for 9.5-10.5" wide tyres, even 10.5" is borderline on wanting an 8" rim.

infact here's a guide: http://www.tyres-pneus-online.co.uk/equ ... dvice.html

from this one

Within the acceptable range of rim widths, one can select wider or narrower rims than the measuring rim. Selection of a wider rim, from within the approved range, (T & RA tables) stiffens the sidewall and improves handling at the expense of handling. If carried too extreme, either too narrow or too wide of a rim, it can result in uneven tread/pavement contact pressure causing uneven wear and potentially reduced traction, or increased vulnerability to bead dis-lodgement. Always check with your Dunlop dealer for permissible rim width options.

Remember - safe clearance must be determined for a particular tire/rim contender and vehicle.

Wider rims may offer some performance advantages over narrow rims. A wider rim increases the distance between the beads, which results in a straighter sidewall, which stiffens it. This results in quicker steering response and higher cornering forces.

Negatively, the straightened sidewall transmits more road shock to the wheel and suspension, placing greater stress on chassis and suspension parts and delivering a harsher ride. The straighter sidewall exposes the rim, making the wheel more susceptible to damage.

A narrower rim pulls the beads closer together, curving the sidewalls. This increased curvature allows the sidewall to flex more readily over bumps and absorb more road shock during driving. This offers a softer ride

This website says that suzuki made a mistake by fitting 205's to a 5.5 inch rim. HMMMM!!!! I wonder if everything on the net is true......

[TZAR]

I have run 30 x 9.50R15 on standard rims no problems at all. That is the 5.5 inch wide standard suzuki wheels. Yes eventually you will get chafing in the bead area BUT you will not roll the tyre of the rim at low pressures as easily as the 15 x 7

i have 31x10.5 on15x7rims there sweet as

no, its a guide and in conjunction with the other link, of which you highlighted from the other article:

Quote:

so suzuki opted to narrow the 'ideal rim width' by just 12.7mm to soften the ride a bit more - and of course not forgetting how lightweight a sierra is that makes perfect sense.

i have some 30x9.5s up the backyard that were on my first zuk.a 1 litre on stock 1 litre rims so im guessing 5.5" and they were fine


aerenandmel off here bought a zuk engineered on 31s on stock 1 litre rims that was pushing it
