Please help with tire size???
I need help with tire size selection.
Finally after 7 years, I bought wheels for my GS
I bought l-sportline model iv 1 piece from a CL member, 18X8.5 with 45 offset all around.
I read rominl's wheel guide and wasn't sure b/c I'm not going with the recommendation
I want to use 245/45, yes 45
because I like to have that extra sidewalls. I know that it will look beefy as D2 described also
I have bilstein shocks now, and will LOWER with eibach springs sitting in my garage for 3 years
So will it rub with the 45 series because 40 is recommended? ANy other cautions or advice, like spacers.....? I won't be doing any BBK so no concerns there.
This is my first time asking for major help regarding any mods.
Thank you guys.

well how about having me answer your question as well 
the offset is good, on the conservative side but at least you are fine.
with the fat 18 tire setup, you get more sidewall, but if you do full lock hard turns or back up the car, it will rub the front and back of the wheel well. no biggie, you shouldnt be going fast anyway
i don't know how low the eibach is, but if it's low enough and you hit big enough of a dip, you will rub the top of teh front wheel well
that's about it

Now I'm undecided. I have to check with the eibachs, but I think they'll give about 1.2-1.5" drop
From what you're saying of the potential rubbings already, I'm afraid it might rub even more when I have load of passengers in the car 
Well, at least this will answer the questions for future member who would want to use the fatter sidewalls.
I will post results and pictures when I decide on the tires.

You are not the first to use this size as there have been NY members with bad roads doing this to help with the ride. My brother in law here in CA is running the same size. I would ask what his offset is but I don't think he'd know. 
The rubbing rominl described has to do with the overall diameter being 1" over spec. You are running at the diameter of guys with 20s so you will experience all the problems like the guys with 20s. Again, with my brother in law, he is at stock height and he is already complaining about rubbing.
These rubs are all intermittent though. You won't really be able to do much about the dips, especially the ones on the freeway while you are going 70-80. This causes the suspension to compress really quickly and the top of the tires will hit the top of the wheel well liner. As for the others, as long as you are careful not to go full lock, you'll be OK. You eventually learn the car's tolerances and adjust your driving to accommodate them.

I'm still a little concerned when I have passengers in the car, esp. in the back seat.
Thank you neo for the input regarding your brother in law's experience.

the rub when hitting a bad dip, i have that still too, but i mod teh fender a bit, and with how low my car is, i still haev to hit a pretty bad dip to get that rub. so personally i wouldn't call that a bad rub. but you will rub with that 1" over spec

I guess one last question.
If I go with 245/45 should I lower the car, considering neo's brother in law already rub with stock height?

The rub he is experiencing has more to do with the diameter (which will also be your issue) so you can't really avoid it. Dropping it won't make it adversely worse. You'll just have to relearn driving in those situations. There is also the matter of offsets. Yours is pretty conservative. I have no idea what his offsets are. He went and got his setup on his own from some wheel/tire shop. They probably spec'ed it for him since he has no clue on width, offsets, ... I doubt he'd be able to tell me even if I asked.

Drop it is-Thank rominl and neo
Thank rominl and neo
I deserve this
and this for having 2nd thoughts about dropping it
And how can I forget rominl's sig????????
IF my offsets are more appropriate, then I shouldn't have to worry about the width then?
Umm, I basically know the answer to that question, just thinking out loud.

well with 8.5 and 10, with the right offset you will have minimal rubbing for sure. and with the oversize tires, you almost just need to worry about the front, top of the fender

I'll make sure to put the heavy people in the back, trunk included
BTW, just received the wheels today
I would like to thank the both of you again for your help.
Somehow, not too many venture into this tire section because it is somewhat misleading due to the description "tire rack's " and it doesn't get much exposure as compared to the 2nd GS, car chat, or clubhouse section.
