My dad always told me if you can't do something right, don't do it at all. Spacers are a bandaid to a fitment issue. Get a proper sized wheel with a proper offset and you won't run into any issues.Why shouldn't I use spacers?
Most forum members are running 20x8.5" with an 21-24mm offset on a 255/45/20. This setup will cause no rubbing no matter how many dead bodies you care to stuff in your trunk. Another alternative is a 275/45/20 for a wider tire.What is the ideal 20" Setup then?
Quite well. Image courtesy of 300CULATER on Helo Cash & Toyo Proxes S/T 255/45/20:Will the 45 series tire be enough to fill my wheel well?
Pirelli P Zero, Continental SportContact 2, Nitto Extreme 555, Falken. Just about every major tire manufacturer now makes an assortmentment of 20" sizes. Avoid cheaper tires like Hankook or Kumo if you can.Who makes a good tire in 20"
You get what you pay for when it comes down to wheels and tires. The cheaper the wheel, the more likely it is to bend on potholes. Wheels CAN be straightened and repaired but only a few times before they become worthless and lose their strength. A fair price for a good set of 20" Wheels and tires will cost anywhere from $2000 on up. $2500 is a very common pricepoint for a reputable brand of wheel with nice tires. Pricing can go all the way up to $5000 for a set of 20" forged multipiece wheels.I can get a full set of wheels and tires shipped to my house for less than $1000. Is this a good deal?
