Dyzza Posted February 23, 2006 Report Posted February 23, 2006 hey fellas i found this pic in the 'my pictures' folder under 'rollas'... i saved it off rollaclub (i think) ages ago. Does anyone know what rims these are ? I'm heaps sick of the rims i have at the moment ... The rims on my car are 15s and i'm just sick of the crappy ride they provide ( well my f@$ked front suspension may have somethin to do with it ...) . I'm also sick of paying $125+ for a half decent tyre. The solution: drop my car on its nuts, and wack some hot 13 x 7s or somethin on it :locked: . These cars looks tops with only a set of 13s on them, just like this foto (courtesy of whoever owns it :) ) : What do y'all think ... Cheers Dyzza Quote
Biggo Posted February 23, 2006 Report Posted February 23, 2006 can't see proper but are they 3 spokes? Lots of old rx3's and dattos use these on em. Quote
Dyzza Posted February 23, 2006 Author Report Posted February 23, 2006 oh here's a better angle ... Yeah nick i found out that the last owner chopped the front suspension for some stupid reason :locked: ... the back is adjustable konis, i guess he ran out of money before he could do the front ? Cheers again ... You'll notice a crappier ride on 13's. Try 14's if its a big issue? More sidewall flex for starters. hmm point taken! I was tryin to avoid low profile tyres, as these have less travel between the road or bump and the rim itself .. hence a bumpier ride. I haven't heard of sidewall flex, I'm guessing its just where the tyre will flex sideways when you hit a bump, making it a bit bouncy ? Dyzza Quote
Dan Posted February 23, 2006 Report Posted February 23, 2006 Yes, pretty much. Because rubber is flexible it will absorb a sideways motion similar to as it would absorb a bump in the road; compress (tyre goes lower profile) then decompress. I presume (not sure) that in severe cases it could cause the tyre to be pushed off its beads, which would not make you a happy chappy. Dan. Quote
coln72 Posted February 23, 2006 Report Posted February 23, 2006 (edited) Those rims look like Dragway 4 spokes(?). 13's wont make your ride bouncy. Ran them on my KE35 (225's on the rear on 6" rims) and never felt I had any problems. Hell it rode better than my VY wagon on 17's. And you would have to be going hard to push a tyre of a rim.......... Edited February 23, 2006 by coln72 Quote
Medicine_Man Posted February 23, 2006 Report Posted February 23, 2006 Looks similar to what you find on some old MK1/MK2 Ford Escorts.. Quote

Corolla Test Pilot Posted February 23, 2006 Report Posted February 23, 2006 Hmmm... The higher the aspect ratio of your tyres, basically, the softer ride they will provide. This is simply because there is a larger cushion of air between road and rim. However, this is making the assumption that all other variables are the same. Tyre pressure has a massive impact on this factor; higher pressure=less compliance in the cushion of air=rougher ride. Another variable is the quality of the tyre. A higher quality tyre will likely offer a rougher ride, due to more plies in the sidewall, as a opposed to the single nylon ply found in shitty chinese tyres. More plies means less flex in the sidewall of the tyre under heavy lateral loads, such as those experienced in hard cornering. Flex is bad because it causes distortion of the tread face, which means far less ability to disperse water, and a smaller contact patch with the road. Rolling a tyre off the rim is likely to occur in older cars (like ours), with supensions that place undue loads on the outside front tyres, which have been specified by the manufacturer with high (75 and higher) aspect ratios, low speed ratings(meaning less rigid under load) and low pressures(such as the 24psi specified in my ke30's owners manual). These specifications are usually a measure to compensate for the poor bump absorption qualities of their primitive suspensions, performance was not a priority. However, us 'rolla drivers can usually get away with just putting about 30psi in them, 'cos a 900kg car isn't much stress on a modern tyre, no matter what brand.

I'd be running about 30psi in a set of 13s with normal profile tyre. Wouldn't something as low as 24psi cause excessive tyre wear? Fricken jap nuts Dyzza Quote
coln72 Posted February 24, 2006 Report Posted February 24, 2006 Hell I consider 30psi low!!!!!! Used to run in the high 30's in my KE35 Quote
jamesrolla Posted February 24, 2006 Report Posted February 24, 2006 I HAVE A SET OF THOSE MAGS IN BLACK WITCH CAME OFF A ta22, i have them with 205 tyres Quote
Dyzza Posted February 24, 2006 Author Report Posted February 24, 2006 I HAVE A SET OF THOSE MAGS IN BLACK WITCH CAME OFF A ta22, i have them with 205 tyres hmm shweet ... i wanna get some the same as those in the above pictures or 14s if they make them. Dyzza Quote
coln72 Posted February 24, 2006 Report Posted February 24, 2006 Personally I'd rather a set of jellybeans. Quote
Tiger Posted February 24, 2006 Report Posted February 24, 2006 They always look tough on a rolla, the jellybeans :locked: Quote
Xany Posted February 24, 2006 Report Posted February 24, 2006 (edited) did someone say jellybeans? I did have 15's on my car, but i think because of the leaf spring setup in the back it was a little too bumpy for me.....so i went back to 14's. Much better ride.
