If you can climb mountains in top gear then you are wasting engine revs all the time you spend driving on flatter ground.
Try the 185s if you cant go with a taller aspect ratio.

Only reason I worry about the weight is for stop and go at times and pulling the hills without a further downshift. Right now most of the hills on common roads I trave it will pull them in 5th gear at 90%+ load and even gain speed very slowly at 100% load without downshift to 4th. On flat ground running in 6th gear it is 40-50%+ load all of the time depending on speed. 6th on flat is same as 5th on most hills I frequent daily. Do not feel it is wasting any rpms or power in 6th on the flat as it barely has the power to accel in this gear. Load will change quickly with any road imperfection, rise, or fall. Maybe I do not understand what you mean by that? I should be able to go with the taller ones per my measurements. I worry mainly on how much suspension up travel is when hitting a bumb in the road while in a curve which would be the only way large two sizes would rub. Maybe I can get someone with a go pro to see how much it flexes in certain conditions.....
