sooberoo Posted February 14, 2008 Posted February 14, 2008 Getting ready to pull the trigger on a set of 18" Rota Tarmac 3' in hypersilver for my 2005 Legacy GT. I will probably end up going with a 225/40/18 tire, just haven't decided what brand or model yet...... Would I be better off with the 7.5 or 8 inch rim width? What would be the advantages or disadvantage of each? Thanks!
Underdog Posted February 14, 2008 Posted February 14, 2008 If you're going to run a 225/40-18 anyways, get the 7.5", less weight the better. If you want to run wider someday, get the 8". The Crimson Dynamo
SubLGTaru Posted February 14, 2008 Posted February 14, 2008 not to thread jack, but do you think the 245/35/18 would look bad on a stock suspension LGT?
Underdog Posted February 14, 2008 Posted February 14, 2008 wider is better. period. 245/35/18 ftw But if he plans on staying with a 225/40-18, the extra .5" doesn't get you anything except added unsprung weight, correct? The Crimson Dynamo
whitetiger Posted February 14, 2008 Posted February 14, 2008 ^it will strech the tire alittle bit more and put more tread on the ground. Plus. .5" of metal wont make such a big weight difference imo.
whitetiger Posted February 14, 2008 Posted February 14, 2008 Is that what she said...? I belive my width is satisfactory;)
EL PAALO Posted February 14, 2008 Posted February 14, 2008 the wider wheel will give a little better feedback because it will make the sidewalls a little stiffer. it also gives you the option of running a 245/35 18 later if you decide you need the extra rubber. all lgt's look strange at stock height.
SubLGTaru Posted February 14, 2008 Posted February 14, 2008 plus the overall diameter of the 245/35/18 is 24.8 compared to 24.6 which is stock on a lgt. So wheel gap wise it shouldn't be much of a diff.
whiteGDB Posted February 15, 2008 Posted February 15, 2008 Ugh, this is the problem most first time wheel buyers have........ buying a set that's too narrow because "tirerack said so" which = weaksauce. This is why the classified forums on here and on NASIOC are littered with for sale threads of weaksauce wheels. With that said, I would never buy an aftermarket wheel that is at least +1" in width. Back when I first bought my 04 STi in 03' and was gonna put 17x8.5 TE37s on, everyone said they were gonna rub including the place that sold them to me. But I had already done all the research and measurement and said whatever. Now 8.5" width is nothing and very common with plenty of 9-10.5" out there on imprezas including 5x100s. Btw, I'm running 18x8.5+48 SSR GT2s with Michelin PS2 245/40/18 lowered on pinks with no rubbing on my specB.
sooberoo Posted February 15, 2008 Author Posted February 15, 2008 I thought the extra half inch wouldn't cause any problems, just thought I'd get some feedback on what some of you had experienced. It's just that the vendor I have been dealing with told me that this what I needed which kind of left me a bit peeved. I am not concerned about the extra weight the 8" wheel will add and the 225 tire choice isn't written in stone. Regarding the tire width, I checked the wheel dimension thread in this sub forum, I thought that I had read somewhere that the fenders would need to be rolled to go up to a 245 tire? Wider would be better..... Thanks for the input!
SubLGTaru Posted February 15, 2008 Posted February 15, 2008 I doubt the fenders need rolled if you go with a 245/35/18 on an 18X8 and you are on stock suspension. If you decide to put springs on, then I would imagine you will have some rubbing if you don't roll the fenders.
Spec B Posted February 15, 2008 Posted February 15, 2008 Tarmac 3's come in 7.5" width? I thought you could only get them in 8" width.
sooberoo Posted February 15, 2008 Author Posted February 15, 2008 Yup,7.5 and 8 " widths http://www.rotawheels.com/tarmac3.php
team23jordan Posted February 15, 2008 Posted February 15, 2008 Ugh, this is the problem most first time wheel buyers have........ buying a set that's too narrow because "tirerack said so" which = weaksauce.

sooberoo Posted February 20, 2008 Author Posted February 20, 2008 In this case the speed shop was recommending the wider wheels. That being said I pulled the trigger on Friday. Wheels should be here towards month end. Now to pick a suitable tire.......
sooberoo Posted February 21, 2008 Author Posted February 21, 2008 I live in Calgary, Alberta. Right now my winter setup is 225/45/17 Hankook Icebears on stock rims. As I will have a dedicated summer setup, I was thinking about going with an UHP summer tire. Then again Calgary got snow at least 1 day for every month of 2000, so a UHP AS might be in order. Tires I have been considering include General Exclaim, Falken 912 or 452, Hankook 107 (or new V12 when available), Kumo ASX or SPT. Lots of choices out there.....
al-gorithm Posted March 4, 2008 Posted March 4, 2008 I wonder what 245/35/18 on a 7.5" tire would do...
