Im buying wheels and tires for my 2012 rs9.0 but im getting confused. I want to go with an 18x8 wheel +45 with trd springs but do not know what tire size to use. Would like 225/40r18 but i dont know if they will rub or not and do not want to use any spacers. Any imput would help!!

Thanks 10glide

 

Yes. 225/45/18 is your guy. no rubbing will occur. your offset is perfect for your car. you'll have zero issues. screw trd though, go tein, if not you'll regret it.

 

Why tien springs? The tires I wanted to use are 225/40r18
Are those still ok?

 

With that 8" width on your rim you might want to go 45 on the profile so you aren't stretching too bad. If you go 40 on the profile, you might be stretching more than you'd like. The other reason I don't recommend it is because this is probably your daily driver and I'd hate for you to hit a bump in the road and bend a rim or pop a tire because your tires are weak at the bead. But yeah, 225/40/18 will fit. Try and go 45 if you can.

Trd springs do not give you a drop worth a dammn. Tein springs give you a really nice drop and especially on that xB it'll look really nice. Read the specs on the springs so you can see what kinda drop youre looking at and seee what you think. If you drop 2 inches or so that will not effect your daily driving what so ever so don't worry about that.

 

On 18x8 +45 wheels, with TRD springs, you should go with 235/40-18 tires if you want a little more meat on the ground and a little bit more sidewall height. No rubbing at all.

 

Try NF 210's great ride quality . Perfect mild drop , better than TRD.

 

Because the guy who recommended them has Teins. Same reason another guy recommended NF210s. Everyone on SL thinks that whatever they have is the best.

 

As someone who had NF's on my 2008 xB, and H-Tech's on my 2012 xB, here's an objective review:

If you want the most comfortable ride with a mild drop, then the NF's are absolutely it; however, with their softer spring rates they will allow more body roll when cornering. They're great springs for high mileage daily driver freeway flyers.

If you want something just a little bit stiffer for handling, is still a mild drop up front, and levels out the rear tire/fender gap better than the NF's, then the H-Tech's are the ticket. Combined with the Tokico HP Blue shocks/struts, this is a great high mileage daily driver combo that is still fun in the twisty stuff.

 

^^^ Now that's a lot more helpful than "Screw brand X, get brand Y or you'll regret it."

FWIW, I've been very happy with my TRD springs for the past 5 years. Same drop as the NF210s but stiffer and better handling. I don't mind the slight rake that remains with TRD, NF210, etc. because it allows the car to remain level when loaded with passengers and/or cargo.

Here is a useful resource for comparing various springs, etc.:

The almost 50% stiffer spring rate of the rear H-Tech springs (compared to the NF) allows the rear to remain level even when loaded with all but the heaviest of passenger/cargo loads... just a little more objectivity.

 

Okay, you win... your springs are the best!

 

As Elvis once said, "Thank you, thank you very much."

 

I have 18x8 on 225/40/18 with NF210s. The ride is not bad at all and I don't like the look of too much sidewall. This set up has been riding pretty good, I live in Michigan (near detroit) mind you and are roads are definitely not smooth.

It looks good, closes wheel gap and not to much sidewall, which show off the rims more!

 

Now that we are stating whos setup is better. MINE IS BETTER.
