Legasee Posted June 20, 2005 Share Posted June 20, 2005 Just wondering if anyone is running with wider tires on LGT rims? 225/45/17 or 225/40/17? Does it fit alright, or are the tires too wide for the 7.0" wide rims? Thanks! (thinking about upgrading my tires) Xenonk's info indicates it'll fit, but I don't want to stretch the rubber too much In Taiwan now... Link to comment Share on other sites More sharing options...

Xenonk Posted June 20, 2005 Share Posted June 20, 2005 all of my are 225/45/17. 40 is too short, unless you are autocrossing the car for just that event. Keefe Keefe Link to comment Share on other sites More sharing options...

SC GT Posted June 20, 2005 Share Posted June 20, 2005 I'm running 225/45/17 RE070s, and I'm slightly lowered. They fit fine. Link to comment Share on other sites More sharing options...
HansGT Posted June 20, 2005 Share Posted June 20, 2005 all of my are 225/45/17. 40 is too short, unless you are autocrossing the car for just that event. Keefe I thought that in one thread you mentioned that the tire width really shouldn't be more than 1.5" wider than the wheel. I'm interested in a 225/45/17 Toyo Proxie4's, but on stock rims the sectional width would be 8.7", is that too much...don't want a lot of sidewall flex? Would I be better off with a 215/45/17 in this tire, it would be a little bit more narrow than an RE92, but the better compound would make up the difference. Your thoughts?

Triple Digits Posted June 20, 2005 Share Posted June 20, 2005 Just remember if you are upping the tire size without getting a lighter rim you might be taking a 2lb per corner penalty with a 225 over a 215... Link to comment Share on other sites More sharing options...

I've got a slightly used set that will be going on if a freind doesn't take them off my hands. Did you notice any change in the ride quality? I don't want to put them on if it makes the ride too harsh. I'm sure your GT corners MUCH better now. Any pics of these tires on your car? oops...sorry for the OT.

The 225 toyo is the same weight as the 215 RE92. Link to comment Share on other sites More sharing options...

Legasee Posted June 20, 2005 Author Share Posted June 20, 2005 I thought you had 18s? I did...but I just sold it cuz I the rears were gonna rub with people sitting int he back seats, plus the rims looked better on other cars. I'm pretty bad, I change my mind on cars and car parts quite a bit, and I want to go with a set of wheels that, just in case I don't like the rims again, I can put the tires onto the factory rims (I know I want wheels, just hate it when "the grass is greener on the other side" ALL THE TIME )...

Guest turboman Posted June 20, 2005 Share Posted June 20, 2005 There once was an old road racing rule that your rims should be at least as wide as your tread, or wider, for the optimum handling. Notice the European Saloon car racing on TV with all their weird cars. All their rims stick out farther than the tires sidewalls. Of course that old rule was before they had 35 & 40 aspect ratio tires. Wider treads don't mean better handling. Too many other factors involved. Just adding two cents worth.

Your thoughts?[/quote'] you can get away with a .2" of a difference as I stated. Just dont go crazy like 2.0" wider than the rim. Remember, the stock rim is 7" wide, but really measures 8" wide (it's pretty close to common practice that most rims are built 1" larger than nominal size). Since you are mounting a 8.7" you are only really adding a .7" wider than the rim.. it's not THAT bad.. it's REALLY bad when you have 1" or more of sectional width (1/2" on each side of the rim wall) to mess with. 225/45/17 on a 7" is just fine. Heck, I even track the car with 7" wide rims with 225/45/17. The turn in response is very minor in delay, I am sure that 90% of you wouldnt be able to feel it. Whatever you guys do, just dont get like a 245/40/17 on a 7" wide wheel. Keefe Keefe Link to comment Share on other sites More sharing options...

Xenonk Posted June 21, 2005 Share Posted June 21, 2005 I never had a rubbing issue with about 300 lbs of track tools in the trunk and another 120 lbs worth of tires and wheels in the back seat and I still dont rub with my 18"x7.5" +40mm offset rims with 225/40/18 R-compound tires. 225/45/17 on a stock 7" wide rim = just fine.

The tire company really wants an 8" when the say 7"?? So really a 235/40/17 isn't looking so bad if it works. Nearly the same diameter, and now only 1.25" larger. If an M3 can run 235/40 on a 17x7.5 we sure can. 235 would make a very nice upgrade.. Link to comment Share on other sites More sharing options...

Legasee Posted June 21, 2005 Author Share Posted June 21, 2005 ^^^you got a point there...they are not as wide...maybe the car gods don't want me rollin in 18's -I'm still trying to decide on my next set... I made a decision on my first post, but then I stumbled on a set of 18's....ahhhhhh!!! back to square one... 18s 18s 18s (17s?) In Taiwan now...

Guest turboman Posted June 21, 2005 Share Posted June 21, 2005 I appreciate it's sort of late, but the next issue of Grassroots Motorsports magazine coming out in August (I think) has an extensive test of our class of tires. I'm hoping slalom time comparisons of 17 VS 18's. Why would anyone want the heavier weight of 18" rims? Can't see what's gained. Plenty of tires in virtually the same dimensions as the lighter 17 inchers. Only reason I can think of is if you wanted to go to aftermarket brakes.

The DSM-crowd from where I originate loves rims and tires, and there are countless technical documentations and discussions on DSMtuners regarding *_actual_* tire-sizing so as to reduce the complaint of members going out to buy wheel & tire combos that "should fit," only to find rubbing problems later on. -A <-- I love Winky, my "periwinkle" (ABP) LGT! - Allen / Usual Suspect "DumboRAT" / One of the Three Stooges '16 Outback, '16 WRX, 7th Subaru Family Link to comment Share on other sites More sharing options...
