I have a 06 997 4, I kind of want to stick to a 18 or 19 inch, the vehicle is not lowered yet, I want to lower it with H & R springs 1.2". What tire size would you guys recommend with this set up to completely get rid of the tire gap.

Please post pics if you have any.

 

Tire size is not arbitrary so its not so much an opinion as it is fact and a quick search will yield exactly 1 or 2 available options for your application. Tire size is correlated to factory rolling diameter spec, which is correlated to accuracy of speedometer.

I can't speak for 18's, but for 19's- I believe 245/35-19, 305/30-19 will be the meatiest i.e. offer tallest sidewall ratio while still keeping within rolling diameter specs. This is narrow body fitment, I assume the same applies for a wide body 4, but lower wheel offset (wider stance), additionally you can use spacers to tweak stance. Dropped on H&R's, you ought to have the most aggressive (least gap) possible without going height adjustable coil overs.

You can refer to my post for an idea of drop on H&R's, however, I am running 235/295, which is factory spec: https://www.6speedonline.com/forums/...w-me-997s.html

 

I didnt find tires in the size you provided so I went with
Tire Size Front: 245/40-19
Tire Size Rear: 305/30-19

would that work?

 

I'm running 245/30-20's and on the rears 305/25-20's

 

The fronts will rub and you will your speedometer will be inaccurate. Stick w. 235/35-19 in the front.

 

If mine don't rub & the speedometer is spot on how is his going to be rubbing and the speedo be off running the same size tires only on 19"s instead of 20"s?
