Hey guys, need some advice on fitment... I'm considering getting R255/35R18 tires in the back and 18" wheels to go with them... Will they fit on 2010 Mazda3 2.5L GT Hatchback? Thanks.

With the proper offset and wheel width they should fit. You're likely to need a fender roll though.

Use this to put in the stock setting and then put in whatever you're expecting, and you can see how much more you'll be past the stock setup, and then how much more inboard you'll be. Make sure you're not too much more inside (to avoid hitting the shock) and depending how much out you go, you'll need to look at a fender roll (I needed it even just with 8.5" wide wheel with a 225 tire on the gen 1).

Figure out your sizing, then go do some measuring.

Great website, thanks for the help. Yeah, they should fit with spacers. Compared to my current setup (225/45R17 ET45), I would have to use 10mm spacers (minimum) for inside clearance. They stick out 17mm beyond my current setup, so combined with the 10mm spacers, they would stick out 27mm. Should be fine because I run 25mm spacers right now and have encountered slight rubbing on bumps/potholes. So it should be a similar situation. Ideally might need a fender roll down the road.

Anyone running 215/40 on 18x8?

I was running a 225/40 last summer with a +35 offset and would rub at the rears on big dips, and even on slight dips when loaded with at least 2 in the back.

I’m wondering if 215/40 would be better. Looking for a new set this coming summer.

I was considering getting the Niche Sector M197 wheel. It's 19X8.5, +35 offset. Currently lowered on Eibach pro kits. Probably with 225/40/r19 tires. Will this fit? Not sure if a 235/35 would work as well
