Sorry if this question's been asked, if so, can you point me in the right direction? I've been searching around before posting this thread.

I have a 2015 IS250 RWD F-Sport dropped on some RSR Down springs
I ordered some Niche Targa wheels for it and wanted to see if anyone had a similar setup. I wanted to see if they had any problems with rubbing.

20x8.5 +35 offset 245/35/20
20x10 +40 offset 275/30/20

Everybody says that with 20s you should get 225/30/20 on front and 255/30/20 on back. But idk man 225/30 just seems to rubberbandish looking. Maybe 235/30?

My set up. Rides perfect. No rubbing.

RSR Down Springs
Front- 20x9 +38 (245/30/20)
Rear- 20x10.5 +42 (255/30/20)

I did have 225/30/20s up front. Too much stretch for me. Really happy with 245s!

I have 245/35 up front and i rub when i turn does a 245/30 make that much of a difference especially lowered ? im awd tho i just ordered similar spec rims

JTLexIS

I have AWD also. Does not rub at full turn riding solo. May rub with packed car tho. I rarely drive with people in the back seat. I drive over bumps on the road at 70 mph, no rub. Smooth as stock.

Thanks for the input, guys. I appreciate it. I just took some quick pics of the car after installing the RSR Down springs yesterday

Im going to try the tires that I posted in the original post out and see. The sidewalls are round. They don't go straight up, so I'll see if it will run or not. Let's hope not

If they rub then I'll probably go with a setup like JTLexIS

Wooooo! Bad choice. Lol. Going to order some new tires to go on now. Any suggestions on brands?

Thinking about doing 24530/20 or 235/30/20 in the front and 255/30/20 in the rear

With RSR Down springs I wouldn't recommend any tires wider than 255 for the rear unless you switch to Half Downs. You might be able to fit 265 with Half Downs without rubbing but either way 255 and 265 is really stretched on 10.5 wheels so you have to drive carefully or you'll damage them. I had 20x9 and 20x10.5 wheels before and was always dodging potholes. Here's a pic of my car with Niche Misano 18x8 and 18x9.5 with RSR Half Downs.

Option 1
Front: 235/30R20
Rear: 255/30R20

Option 2
Front: 245/30R20
Rear: 255/30R20

Thanks for the input! I putting Niche Misano's on as well. Really leaning towards going with the 255/30/20 for the rear and 235/30/20 for the front and rolling the fenders. Trying to reduce as much rub as possible. Yeah my buddy had a set of 275/30/20 and 245/35/20 in the Continental ExtremeContact DWS and he said to use them. He was going to put them on his GS. I got them installed and had to take them off right away.

Alright, here's and update. I went with the Sumitomo HTR Z III tires. 255/30/20 in the rear and 235/30/20 in the front. I am on RSR down springs. No camber kit on yet, but I'll be having SPC rear cambers on.

No rubbing so far. Fingers crossed.
